Primitive Colors

Author(s):  
Joshua Gert

This book is both an account of the nature of color and color perception, and an exercise in neo-pragmatist theorizing. Neo-pragmatism rejects representationalism, which is the standard strategy for solving “placement problems” in philosophy. Instead, it makes use of deflationary accounts of truth and reference. In the domain of color, the result is color primitivism: a view of color according to which colors are sui generis properties of objects, irreducible to physical or dispositional properties. Objective colors are also—contrary to current dogma—insufficiently determinate in their nature to allow them to be associated with precise points in standard color spaces. Rather, standard color spaces are appropriate for the description of color appearances, which are to be understood in line with a moderate form of adverbialism. A central analogy here is between the perceptible three-dimensional shape of an object and the various ways in which that shape appears from various perspectives. The book also offers an account of color constancy, a moderated version of representationalism about visual experience, and a criticism of the thesis of the transparency of experience. Also included are detailed discussions of rival views, including those of Alex Byrne and David Hilbert, C. L. Hardin, Jonathan Cohen, Mark Kalderon, Keith Allen, and Derek Brown.

This article examines the relatively new fields of colour and shape trade marks. It was initially feared by some academics that the new marks would encroach on the realms of patent and copyright.  However, the traditional requirements of trade mark law, such as functionality and descriptiveness, have meant that trade marks in colour and shape are extremely hard to acquire if they do not have factual distinctiveness. As colour and shape trade marks have no special restrictions, it is proposed that the combination trade mark theory and analysis from the Diamond T case should be used as a way to make them more accessible. The combination analysis can be easily applied because every product has a three dimensional shape and a fourth dimension of colour.

Perceiving the shape of three-dimensional objects is essential for interacting with them in daily life. If objects are constructed from different materials, can the human visual system accurately estimate their three-dimensional shape? We varied the thickness, motion, opacity, and specularity of globally convex objects rendered in a photorealistic environment. These objects were presented under either dynamic or static viewing condition. Observers rated the overall convexity of these objects along the depth axis. Our results show that observers perceived solid transparent objects as flatter than the same objects rendered with opaque reflectance properties. Regional variation in local root-mean-square image contrast was shown to provide information that is predictive of perceived surface convexity.
