Color is a fundamental aspect of normal visual experience. This chapter provides an overview of the role of color in human behavior, a survey of current knowledge regarding the genetic, retinal, and neural mechanisms that enable color vision, and a review of inherited and acquired defects of color vision including a discussion of diagnostic tests.

Color vision

Ophthalmology Clinics of North America, 2003
Many visual disorders produce acquired color vision defects. Color vision theory emphasizes several stages of visual processing: prereceptoral filters (lens, macular pigment, pupil), cone photopigments (L-, M-, and S-cones), and postreceptoral processes (red-green, S-cone, and luminance channels).

Blobs and Color Vision

Cell Biophysics, 1986
Two main topics will thread their way through this paper: The structure of the monkey striate cortex, including its inputs and outputs, and the physiological basis of color vision. When Margaret Livingstone and I began this work four years ago we did not set out to study color, but the structures in the cortex that we have been looking at turn out to ...
