A Naive Realist Theory of Colour defends the view that colours are mind-independent properties of things in the environment, that are distinct from properties identified by the physical sciences. This view stands in contrast to the long-standing and wide-spread view amongst philosophers and scientists that colours don't really exist - or at any rate, that if they do exist, then they are radically different from the way that they appear. It is argued that a naive realist theory of colour best (...) explains how colours appear to perceiving subjects, and that this view is not undermined either by reflecting on variations in colour perception between perceivers and across perceptual conditions, or by our modern scientific understanding of the world. A Naive Realist Theory of Colour also illustrates how our understanding of what colours are has far-reaching implications for wider questions about the nature of perceptual experience, the relationship between mind and world, the problem of consciousness, the apparent tension between common sense and scientific representations of the world, and even the very nature and possibility of philosophical inquiry.

Can the phenomenal character of perceptual experience be altered by the states of one's cognitive system, for example, one's thoughts or beliefs? If one thinks that this can happen then one thinks that there can be cognitive penetration of perceptual experience; otherwise, one thinks that perceptual experience is cognitively impenetrable. I claim that there is one alleged case of cognitive penetration that cannot be explained away by the standard strategies one can typically use to explain away alleged cases. The case (...) is one in which it seems subjects' beliefs about the typical colour of objects affects their colour experience. I propose a two-step mechanism of indirect cognitive penetration that explains how cognitive penetration may occur. I show that there is independent evidence that each step in this process can occur. I suspect that people who are opposed to the idea that perceptual experience is cognitively penetrable will be less opposed to the idea when they come to consider this indirect mechanism and that those who are generally sympathetic to the idea of cognitive penetrability will welcome the elucidation of this plausible mechanism.

We say "the grass is green" or "lemons are yellow" to state what everyone knows. But are the things we see around us really colored, or do they only look that way because of the effects of light rays on our eyes and brains? Is color somehow "unreal" or "subjective" and dependent on our human perceptions and the conditions under which we see things? Distinguished scholar Barry Stroud investigates these and related questions in The Quest for Reality. In this (...) long-awaited book, he examines what a person would have to do and believe in order to reach the conclusion that everyone's perceptions and beliefs about the color of things are "illusions" and do not accurately represent the way things are in the world as it is independently of us. Arguing that no such conclusion could be consistently reached, Stroud finds that the conditions of a successful unmasking of color cannot all be fulfilled. The discussion extends beyond color to present a serious challenge to many other philosophical attempts to discover the way things really are. A model of subtle, elegant, and rigorous philosophical writing, this study will attract a wide audience from all areas of philosophy. (shrink)

"This admirable volume of readings is the first of a pair: the editors are to be applauded for placing the philosophy of color exactly where it should go, in ...

Some philosophical theories of the nature of color aim to respect a "common sense" conception of color: aligning with the common sense conception is supposed to speak in favor of a theory and conflicting with it is supposed to speak against a theory. In this paper, we argue that the idea of a "common sense" conception of color that philosophers of color have relied upon is overly simplistic. By drawing on experimental and historical evidence, we show (...) how conceptions of color vary along several dimensions and how even supposedly "core" components of the contemporary "common sense" conception of color are less stable than they have been thought to be.

The words “content” and “character” in my title refer to the representational content and phenomenal character of color experiences. So my topic concerns the nature of our experience of color. But I will, of course, be talking about colors as well as color experience. Let me set the stage by mentioning some things, some more controversial than others, that I will be taking for granted. I assume, to begin with, that objects in the world have colors, and (...) have them independently of being perceived to have them, and independently even of there being creatures capable of perceiving them. I think, and this of course sets me apart from the many color irrealists among philosophers and color scientists, that any reasonable semantics for color terms, and any reasonable account of the reference of color concepts, should yield the result that colors are properties of external things that are realized in certain of their physical properties, namely those responsible for their reflecting or emitting the light whose impact on our retinas is involved in causing our color perceptions. This brings me to a further assumption that I shall be making, namely the truth of physicalism. I take physicalism to be the thesis that all properties of things either are or are realized in basic physical properties, where basic physical properties are the properties that underlie the behavior and causal powers of inanimate things. There are two ways in which the commitment to physicalism will figure in my discussion. First, I assume that colors are physically realized properties. Second, I assume that color experiences are physically realized. These two commitments frame the problem I am discussing – how can colors be properties realized in the microphysical properties of things, and how can color experience be so realized? I don’t think there is any generally accepted account of what it is for a property to be “realized in” other properties. For those who think, as I do, that properties are individuated by their causal features, it should seem plausible to say that property P realizes property Q just in case the forward looking causal features of Q are a subset of the forward looking causal features of P, and the backward looking....

Perspectivalism is a semantic theory according to which the contents of utterances and mental states (perhaps of a particular kind) have a truth-value only relative to a particular perspective (or standard) determined by the context of the speaker, assessor, or bearer of the mental state. I have defended this view for epistemic terms, moral terms and predicates of personal taste elsewhere (Brogaard 2008a, 2008b, forthcoming a). The main aim of this paper is to defend perspectivalism about color perception and (...) color discourse. The content of color perception and color discourse, I will argue, has a truth-value only relative to an appropriate viewing condition and the perceiver, or a perceiver deferred to. (shrink)

UK Higher Education is characterised by structural and institutional forms of whiteness. As scholars and activists are increasingly speaking out to testify, whiteness has wide-ranging implications that affect curricula, pedagogy, knowledge production, university policies, campus climate, and the experiences of students and faculty of colour. Unsurprisingly then, calls to decolonize the university abound. In this article, we draw upon the Critical Race Theory method of counter-storytelling. By introducing composite characters, we speak back to assumptions that universities are race-neutral, meritocratic institutions. (...) We illustrate some of the key themes that shape the experiences of faculty of colour in UK Higher Education: institutional racism, racial microaggressions, racial battle fatigue, and steadfast fugitive resistance. We argue that, despite the paradox of working under (what purports to be) a ‘decolonial’ agenda, widespread calls to decolonize our universities have further embedded rather than dismantled whiteness, thus continuing to characterise the careers, wellbeing, and daily lives of faculty of colour.

The standard adaptationist explanation of the presence of a sensory mechanism in an organism—that it detects properties useful to the organism—cannot be given for color vision. This is because colors do not exist. After arguing for this latter claim, I consider, but reject, nonadaptationist explanations. I conclude by proposing an explanation of how color vision could have adaptive value even though it does not detect properties in the environment.

Categorical perception (CP) is said to occur when a continuum of equally spaced physical changes is perceived as unequally spaced as a function of category membership (Harnad, S. (Ed.) (1987). Psychophysical and cognitive aspects of categorical perception: A critical overview. Cambridge: Cambridge University Press). A common suggestion is that CP for color arises because perception is qualitatively distorted when we learn to categorize a dimension. Contrary to this view, we here report that English speakers show no evidence of lowered (...) discrimination thresholds at the boundaries between blue and green categories even though CP is found at these boundaries in a supra-threshold task. Furthermore, there is no evidence of different discrimination thresholds between individuals from two language groups (English and Korean) who use different color terminology in the blue-green region and have different supra-threshold boundaries. Our participants' just noticeable difference (JND) thresholds suggest that they retain a smooth continuum of perceptual space that is not warped by stretching at category boundaries or by within-category compression. At least for the domain of color, categorical perception appears to be a categorical, but not a perceptual phenomenon. (shrink)

Social justice is put forth as a core professional nursing value, although conceptualizations within foundational documents and among nurse educators remain inconsistent and contradictory. The purpose of this study was to explore how faculty teach social justice in theory courses in Baccalaureate programs. This qualitative study utilized constructivist grounded theory methods to examine processes informing participants' teaching. Participants utilize four overarching approaches: fostering engaging classroom climates, utilizing various naming strategies, framing diversity and culture as social justice, and role modeling a (...) critical stance. They deploy specific strategies, varying largely by race, educational background, and nursing specialty. A background in social sciences supports pedagogy that interrogates health inequities rather than merely raising awareness about disparities. Findings also reveal that faculty of color navigate institutional structures predicated upon colorblind racism and problematic views of culture, which many white faculty teaching non‐Community Health Nursing courses described doing. To enact social justice and be answerable to our communities, concerted anti‐oppression efforts are needed across education, research, practice, and policy. This includes sustained commitment to address colonialism and whiteness in every institution that defines, promotes, and claims to advance nursing so that we can fulfill our responsibility to address unjust systems and structures to serve our communities.

How, if at all, does the internal structure of human phenomenological color space map onto the internal structure of objective reflectance‐profile space, in such a fashion as to provide a useful and accurate representation of that objective feature space? A prominent argument (due to Hardin, among others) proposes to eliminate colors as real, objective properties of objects, on grounds that nothing in the external world (and especially not surface‐reflectance‐profiles) answers to the well‐known and quite determinate internal structure of human (...) phenomenological color space. The present paper proposes a novel way to construe the objective space of possible reflectance profiles so that (1) its internal structure becomes evident, and (2) that structure’s homomorphism with the internal structure of human phenomenological color space becomes obvious. The path is thus reopened to salvage the objective reality of colors, in the same way that we preserved the objective reality of such features as temperature, pitch, and sourness—by identifying them with some objective feature recognized in modern physical theory.

What knowledge of the colors does perception of the colors provide? My first aim in this essay is to characterize the way in which color experience seems to provide knowledge of colors. This in turn tells us something about what it takes for there to be colors. Color experience provides knowledge of the aspect of the world that is being acted on when we, or some external force, act on the color of an object and thus make (...) a difference to the experiences of people looking at it. It is in this sense that the nature of the colors is transparent to us. For there to be colors is for there to be the qualitative categorical properties that we encounter in perception, action on which affects the color experiences of observers. This line of thought contrasts with the idea that color experience reveals the colors to us, in the sense that it provides knowledge of a number of necessary truths about the colors. In a recent paper, Alex Byrne and David Hilbert provide a careful exposition and critique of this way of developing the idea of color experience as revelatory of the colors. In this paper my main aim is simply to contrast the idea that experience makes the colors transparent to us, with the idea that color experience provides us with knowledge of truths relating to the essences of the colors.

The paper reviews the empirical evidence for highly significant variation across perceivers in hue perception and argues that color physicalism cannot accommodate this variability. Two views that can accommodate the individual differences in hue perception are considered: the self-locating property theory, according to which colors are self-locating properties, and color relationalism, according to which colors are relations to perceivers and viewing conditions. It is subsequently argued that on a plausible rendition of the two views, the self-locating theory has (...) a slight advantage over color relationalism in being truer to the phenomenology of our color experiences.

One of the most important objections to sense data theory comes from the phenomenon of indeterminate perception, as when an object in the periphery of one’s visual field looks red without looking to have any determinate shade of red. As sense data are supposed to have precisely the properties that sensibly appear to us, sense data theory evidently has the implausible consequence that a sense datum can have a determinable property without having any of its determinates. In this article, I (...) show that a parallel objection applies to standard forms of colour relationism. In light of the phenomenon of indeterminate perception, the colour relationist must either reject intuitively obvious claims about the determinate–determinable structure of colour space or reject the plausible and widely accepted principle that nothing can have a determinable without having one of its determinates.

Poorly saturated colors are closer to a pure grey than strongly saturated ones and, therefore, appear less “colorful”. Color saturation is effectively manipulated in the visual arts for balancing conflicting sensations and moods and for inducing the perception of relative distance in the pictorial plane. While perceptual science has proven quite clearly that the luminance contrast of any hue acts as a self-sufficient cue to relative depth in visual images, the role of color saturation in such figure-ground organization (...) has remained unclear. We presented configurations of colored inducers on grey ‘test’ backgrounds to human observers. Luminance and saturation of the inducers was uniform on each trial, but varied across trials. We ran two separate experimental tasks. In the relative background brightness task, perceptual judgments indicated whether the apparent brightness of the grey test background contrasted with, assimilated to, or appeared equal (no effect) to that of a comparison background with the same luminance contrast. Contrast polarity and its interaction with color saturation affected response proportions for contrast, assimilation and no effect. In the figure-ground task, perceptual judgments indicated whether the inducers appeared to lie in front of, behind, or in the same depth with the background. Strongly saturated inducers produced significantly larger proportions of foreground effects indicating that these inducers stand out as figure against the background. Weakly saturated inducers produced significantly larger proportions of background effects, indicating that these inducers are perceived as lying behind the backgrounds. We infer that color saturation modulates figure-ground organization, both directly by determining relative inducer depth, and indirectly, and in interaction with contrast polarity, by affecting apparent background brightness. The results point towards a hitherto undocumented functional role of color saturation in the genesis of form, and in particular figure-ground percepts in the absence of chromatostereopsis. (shrink)

Canadian Schools of Nursing rest upon white, colonial legacies that have shaped and defined what is valued as nursing knowledge and pedagogy. The diversity that exists in clinical nursing and is emerging within the graduate student population is not currently reflected within nursing faculty and academic leadership. Black, Indigenous, and People of Color (BIPOC) nurse leaders, historically and presently, are repeatedly left unacknowledged as knowers and keepers of nursing knowledge. This lack of diversity persists across nursing knowledge generation, research, (...) and healthcare practices that ultimately aim to serve the increasingly diverse Canadian population. This narrative inquiry study examined the experiences of eight BIPOC graduate nursing students as they navigated white academic nursing spaces. The findings are presented to reflect their experiences of entrenched in whiteness, erasure of identity, and navigating belonging. These study findings highlight the importance of surfacing academic nursing history shaped by colonialism and racism, the need to diversify nursing faculty and the graduate nursing student population, and implementing nursing curricular and syllabi audits to ensure that they reflect the multitude of ways of knowing to expand dominant Eurocentric and Western knowledge in nursing education.

This essay engages Chandra Mohanty, M. Jacqui Alexander, and María Lugones in a “plurilogue” to elaborate and exhibit a method that animates the differential mode of Women of Color politics while rendering more acute the strategies each scholar offers against the racialized, gendered oppressions of colonialism and global capitalism. Ella Shohat describes “a multifaceted plurilogue” as a “dissonant polyphony” that “links different yet co-implicated constituencies and arenas of struggle” (Shohat 2001, 2). The emphasis on reading differences within Women of (...) Color theorizing resists the homogenizing tendency of superficial engagement that glosses Women of Color scholarship as a unified genre of thought. A plurilogue thus pursues dissimilarities to clarify the conceptual interventions made within Women of Color theorizing and the relationship among the different patterns of oppression that each intervention exposes. Plurilogued engagements bring these conceptual strategies and understandings of multiple oppressions together, not to resolve or rank them, but to more effectively ascertain the complexities of, and varied coalitional strategies for, resisting the racialized, heteropatriarchal oppressions of global capitalism and colonialism.

Summary In the visual arts, the constructions of the spatial and chromatic structures of pictures can hardly be separated from each other. The phenomenological approach from the perspective of the arts provides an independent and worthwhile approach to the topic of colour and space. We address some matters of composition in design and, to some extent, in naturalistic painting. The phenomenological approach from the perspective of the arts reveals various topics that invite further investigation by the means of generic vision (...) science. However, although such studies might lead to increased academic insight, a thorough inquiry by the means of experimental phenomenology might well lead to formal descriptions that come somewhat closer to possible applications in the visual arts.

This entry outlines relationalism, primitivism, and eliminativism about color and considers objections to each theory.

Data about perceptual variation motivate the ecumenicist view that distinct color representations are mutually compatible. On the other hand, data about agreement and disagreement motivate making distinct color representations mutually incompatible. Prima facie, these desiderata appear to conflict. I’ll lay out and assess two strategies for managing the conflict—color relationalism, and the self-locating property theory of color—with the aim of deciding how best to have your cake and eat it, too.

For over a century, the question of the relation of language to thought has been extensively discussed in the case of color categorization, where two main views prevail. The relativist view claims that color categories are relative while the universalistic view argues that color categories are universal. Relativists also argue that color categories are linguistically determined, and universalists that they are perceptually determined. Recently, the argument for the perceptual determination of color categorization has been undermined, (...) and the relativist view has regained some ground. This paper argues that although the universalistic account of color categorization has been called into question, this is not enough to establish relativism. Color categories can still be said to be universal or particular, independent of the accounts of their universality or relativity. Because of its polarization, the debate has disregarded some issues that are key in our understanding of color categorization: the question of what a color category is and how to identify it.

Research on the U.S. women’s movement has documented the difficulties of cross-racial work between White women and women of racial/ethnic minorities. Less understood is how racial/ethnic minorities do cross-racial work among themselves to construct a collective identity of “women of color” that encourages solidarity across race, class, and other statuses. Drawing on research from the reproductive justice movement, I examine how women of color organizations that strive for intersectional praxis negotiate sameness and difference. I identify two different logics (...) at work within women of color organizations: the first relies on a presumption of “same difference” that emphasizes similar experiences of gender and race oppression; the second accords greater recognition to the “difference-in-sameness” that structures constituents’ lived experiences. While the former can reproduce precisely those forms of silencing and exclusion that women of color organizations seek to challenge, the second remains a ongoing process. The article concludes that women of color organizations must strive continuously to actively negotiate, rather than assume, commonality if they are to avoid reproducing various forms of marginalization and inequality.

The subject of the study is color symbolism in F. Fitzgerald’s novel «The Great Gatsby» in the aspect of an ambivalent understanding of the conceptual solution in the use of a certain color in creating images of characters, in describing the setting and semantic content of the ideological content of the work and its screen interpretations. The object of study is color as a meaning-forming concept in literature and cinema, the symbolism of color. The work of (...) Francis S. Fitzgerald «The Great Gatsby» is of interest in the study of the influence of color palette. The main research methods are analytical and comparative historical. The color concepts of F. S. Fitzgerald's book “The Great Gatsby” and film adaptations are comprehended. This work by F. S. Fitzgerald is of interest to the modern Russian reader and viewer due to the fact that the problems raised in the novel are still relevant today. The writer touches on the popular theme of the American dream in literature and cinema. The story of the main characters is a vivid example of the illusory nature of this dream, and the lifestyle of the characters and their worldview demonstrate spiritual emptiness and cold indifference to everything except money and wealth. The scientific novelty of the article lies in the study of the ambivalence of perception of the coloristic solution of the images of characters in the book in comparison with its screen interpretations. The author comes to the conclusion that F. S. Fitzgerald in the novel «The Great Gatsby» uses a color palette in creating images of characters and describing the scene in such a way that the ambiguity in the perception of color most unexpectedly and sharply emphasizes the problems raised and becomes the basis for rethinking the ideological content of the work.

Are the following propositions true of the colors: No object can be more than one determinable or determinate color all over at the same time (Incompatibility); the colors of objects are mind-independent (Objectivism); and most human observers usually perceive the colors of objects veridically in typical conditions (Veridicality)? One reason to think not is that the empirical literature appears to support the proposition that there is mass perceptual disagreement about the colors of objects amongst human observers in typical conditions (...) (P-Disagreement). In this article, we defend Incompatibility, Objectivism, and Veridicality by calling into question whether the empirical literature really supports P-Disagreement. (shrink)

In this paper I challenge the core of David Chalmers' argument against materialism-the claim that "there is a logically possible world physically identical to ours, in which the positive facts about consciousness do not hold." First, I analyze the move from conceivability to logical possibility. Following George Seddon, I consider the case of a floating iron bar and argue that even this seemingly conceivable event has implicit logical contradictions in its description. I then show that the distinctions Chalmers employs between (...) primary and secondary intensions, and a priori and a posteriori entailment, break down upon close examination-with iron bars and with consciousness it is impossible to know where primary intensions end and secondary intensions begin. I extend this analysis of logical possibility to the famous zombie thought experiment and conclude not that a zombie world is logically impossible, but rather that, at present, the question is open. Finally, I show how a similar line of argument may be used to undermine the "Mary the color scientist" thought experiment as well. (shrink)
