Chromatic adaptation and the blue-green side of the color triangle. 1983

G A Fry

This is an attempt to show with chromatic adaptation data that the line tangent to the spectrum locus at about 460 nm and passing through the tritanopic confusion point represents the blue-green leg of the triangle of fundamental colors. The inability to use chromatic adaptation to produce colors in the green corner of the triangle has been explained in terms of a zone theory of color vision.

D003116	Color	The visually perceived property of objects created by absorption or reflection of specific wavelengths of light.	Colors
D003118	Color Perception	Mental processing of chromatic signals (COLOR VISION) from the eye by the VISUAL CORTEX where they are converted into symbolic representations. Color perception involves numerous neurons, and is influenced not only by the distribution of wavelengths from the viewed object, but also by its background color and brightness contrast at its boundary.

D000221	Adaptation, Ocular	The adjustment of the eye to variations in the intensity of light. Light adaptation is the adjustment of the eye when the light threshold is increased; DARK ADAPTATION when the light is greatly reduced.
