Color-vision demonstrations on an IBM PC/AT with VGA

The program CVD contains a set of color-vision demonstrations. They include plain color fields with surrounds, cross-context matching, spatial brightness and color contrast transfer, and adaptation. Also available are displays used in flicker photometry, additive color mixing, color order systems, and the diagnosis of color-vision defects. Simulations of experimental setups allow demonstrations of actual experimental methods and effects. Any color field may be modified, and adjustments are simultaneously displayed in a CIEx,y chromaticity diagram. Most demonstrations include a context-dependent, introductory help text with references.
