Color Appearance Mode and perception of surface

―no brown light source as the imperceptible color―

Abstract

Color vision is caused by the processing of information on cones on the retina by the opposite color mechanism. Now, is the appearance of the color determined only by the light analysed by this neural mechanism?

In the situation where we usually perceive color, it is often against the reflected light from the surface of an object. On the other hand, color perception also occurs for light sources. If both lights have the same spectral energy distribution, these should cause identical results of color appearance in both cases for the cones. However, we can often describe the difference between whether the object is emitting light or perceiving it as reflected light from an object. It is known that this difference can be explained by the concept of color appearance mode. Here, I am addressing recent findings on the mechanism deriving this color mode and, on the roles, to its mechanism, of the texture that makes the surface of an object perceived.
