  1. Unique Hues and Colour Experience.Mohan Matthen - forthcoming - In Fiona Macpherson & Derek Brown (eds.), Routledge Handbook of the Philosophy of Colour.
    In this Handbook entry, I review how colour similarity spaces are constructed, first for physical sources of colour and secondly for colour as it is perceptually experienced. The unique hues are features of one of the latter constructions, due initially to Hering and formalized in the Swedish Natural Colour System. I review the evidence for a physiological basis for the unique hues. Finally, I argue that Tye's realist approach to the unique hues is a mistake.

    Constant Hue Bands in Boundary Colors Discovered Using a New Appearance Model.Carl Jennings & L. Adams - 2015 - Color Research and Application 40 (2):135-146.
    Boundary colors are observed when light from a scene is dispersed by a prism or diffraction grating. We discovered that patterns with repeating black and white stripes can produce repeating bands of boundary colors with two hues. These hues are virtually constant as measured by chromaticity or CIELAB. We found seven cases of this kind using a new appearance model for boundary colors. The model correctly predicts that green and magenta bands recur as stripe widths and dispersion strength (...)

  4. What is Visual and Phenomenal but Concerns Neither Hue nor Shade?Pete Mandik - 2013 - In Richard Brown (ed.), Consciousness Inside and Out: Phenomenology, Neuroscience, and the Nature of Experience.
    Though the following problem is not explicitly raised by her, it seems sufficiently similar to an issue of pertinence to Akins's "Black and White and Color" (this volume) to merit the moniker, Akins's Problem : Can there be a visual experience devoid of both color phenomenology and black-and-white phenomenology? The point of the present paper is to draw from Akins's paper the materials needed to sketch a case for a positive answer to Akins's Problem. I am unsure about how much (...)

  5. Color Realism: True or Not?Z. G. ma - 2017 - Asian Research Journal of Arts and Social Sciences 4 (4):01-05.
    Color realism refers to that things are colored, or colors are real. Although the view goes in a minority opinion, Byrne & Hilbert defend it based on the physical properties of color and the peculiarly assumed hue-magnitudes. However, hues are mind-dependent and cannot be used as a measure of the physical properties of things. As a result, the defense fails to justify the proposition of color realism.

  6. Effects of Saturation and Contrast Polarity on the Figure-Ground Organization of Color on Gray.Birgitta Dresp-Langley & Adam Reeves - 2014 - Frontiers in Psychology 5:1-9.
    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 (...)

  7. Colour Resemblance and Colour Realism.Fabian Dorsch - 2010 - Rivista di Estetica 43:85-108.
    One prominent ambition of theories of colour is to pay full justice to how colours are subjectively given to us; and another to reconcile this first-personal perspective on colours with the third-personal one of the natural sciences. The goal of this article is to question whether we can satisfy the second ambition on the assumption that the first should and can be met. I aim to defend a negative answer to this question by arguing that the various kinds of experienced (...)

  8. Do We Conceptualize Every Color We Consciously Discriminate?Jacob Berger - 2012 - Consciousness and Cognition 21 (2):632-635.
    Mandik (2012)understands color-consciousness conceptualism to be the view that one deploys in a conscious qualitative state concepts for every color consciously discriminated by that state. Some argue that the experimental evidence that we can consciously discriminate barely distinct hues that are presented together but cannot do so when those hues are presented in short succession suggests that we can consciously discriminate colors that we do not conceptualize. Mandik maintains, however, that this evidence is consistent with our deploying a (...)

  9. Interaction of Color and Geometric Cues in Depth Perception: When Does Red Mean "Near"?Christophe Guibal & Birgitta Dresp - 2004 - Psychological Research 69:30-40.
    Luminance and color are strong and self-sufficient cues to pictorial depth in visual scenes and images. The present study investigates the conditions Under which luminance or color either strengthens or overrides geometric depth cues. We investigated how luminance contrasts associated with color contrast interact with relative height in the visual field, partial occlusion, and interposition in determining the probability that a given figure is perceived as ‘‘nearer’’ than another. Latencies of ‘‘near’’ responses were analyzed to test for effects of attentional (...)

    Human Symmetry Uncertainty Detected by a Self-Organizing Neural Network Map.Birgitta Dresp-Langley - 2021 - Symmetry 13:299.
    Symmetry in biological and physical systems is a product of self-organization driven by evolutionary processes, or mechanical systems under constraints. Symmetry-based feature extraction or representation by neural networks may unravel the most informative contents in large image databases. Despite significant achievements of artificial intelligence in recognition and classification of regular patterns, the problem of uncertainty remains a major challenge in ambiguous data. In this study, we present an artificial neural network that detects symmetry uncertainty states in human observers. To this (...)

  11. Explaining Colour Phenomenology: Reduction Versus Connection.Nicholas Unwin -
    A major part of the mind–body problem is to explain why a given set of physical processes should give rise to qualia of one sort rather than another. Colour hues are the usual example considered here, and there is a lively debate between, for example, Hardin, Levine, Jackson, Clark and Chalmers as to whether the results of colour vision science can provide convincing explanations of why colours actually look the way they do. This paper examines carefully the type of (...)

    Color Constancy: Phenomenal or Projective?Adam J. Reeves, Kinjiro Amano & David H. Foster - 2008 - Perception and Psychophysics 70:219-228.
    Naive observers viewed a sequence of colored Mondrian patterns, simulated on a color monitor. Each pattern was presented twice in succession, first under one daylight illuminant with a correlated color temperature of either 16,000 or 4,000 K and then under the other, to test for color constancy. The observers compared the central square of the pattern across illuminants, either rating it for sameness of material appearance or sameness of hue and saturation or judging an objective property—that is, whether its change (...)

  13. Is Colour Composition Phenomenal?Vivian Mizrahi - 2009 - In D. Skusevich & P. Matikas (eds.), Color Perception: Physiology, Processes and Analysis. Nova Science Publishers.
    Most philosophical or scientific theories suppose that colour composition judgments refer to the way colours appear to us. The dominant view is therefore phenomenalist in the sense that colour composition is phenomenally given to perceivers. This paper argues that there is no evidence for a phenomenalist view of colour composition and that a conventionalist approach should be favoured.

    Emergence of Consciousnesses Shows the Hardness of the Hard Problem of Consciousness.Rajakishore Nath - 2006 - Journal of Indian Council of Philosophical Research 23 (2):167-181.
    I have argued that emergentism is a non-computational theory of mind, because this theory says that mind or consciousness emerges from material objects, but it will not be reduced to that matter. That is to say that the higher level of quality emerge from a lower level of existence. It emerges therefrom, and does not belong to that level, but constitutes its possessor a new order of existence with its social laws of behaviour. Thus, emergentism is an anti-reductionists' theory of (...)

  15. Reflectance Physicalism About Color: The Story Continues.Zoltan Jakab - 2012 - Croatian Journal of Philosophy 12 (3):463-488.
    A stubborn problem for reflectance physicalism about color is to account for individual differences in normal trichromat color perception. The identification of determinate colors with physical properties of visible surfaces in a universal, perceiver-independent way is challenged by the observation that the same surfaces in identical viewing conditions often look different in color to different human subjects with normal color vision. Recently, leading representatives of reflectance physicalism have offered some arguments to defend their view against the individual differences challenge. In (...)

    Mind: A Connectionist Model.Nath Rajakishore - 2004 - Journal of Indian Council of Philosophical Research 21 (3-4):43-62.
    In cognitive science, there are many computational theories regarding the function of the mind; connectionism is one of them. Connectionist networks are intricate systems of simple units related to their environment. Some have thousands of units, but those with only a few units can also behave with surprising complexity and subtlety. This is because processing occurs in parallel as also interactively, in marked contrast with the serial processing to which this is accustomed. In the first section of this paper, I (...)
