What is the relationship between color vision and psychology?
Handbook of Color Psychology We perceive color everywhere and on everything that we encounter in daily life. Color science has progressed to the point where a great deal is known about the mechanics, evolution, and development of color vision, but less is known about the relation between color vision and psychology.

Why does color look different when the illuminant is changed?
First, color appearance does vary somewhat when the illuminant is changed: color constancy is not perfect. predicted for a visual system with no constancy. visual system with perfect constancy. For natural viewing conditions when only the range 0.8-0.9, and sometimes higher. Constancy is not always good, however.

How do color signals affect a scene?
Essentially all current theories share in common object is affected by the color signals reflected from the other objects in the scene. color signal relative to the rest of the retinal image. fundamentals of human color vision. The color signal arriving at each retinal

What is a color signal reflected to the eye?
The spectrum reflected to the eye is thus C(λ) = I (λ) S(λ). We call C(λ) the color signal. Ambiguity arises because of the symmetric role played by I(λ) and S(λ) in the formation of the color signal. For example, a banana seen in counteracted by the change in surface reflectance.

11.2 VISION AND VISION OPTICS Color constancy. The tendency of objects to retain their color appearance despite changes in the spectral characteristics of the illuminant, or, more generally, despite changes in viewing context. Color contrast. The change in the color appearance of an area caused by the presence of a colored surround.

Initiatives from the academy, industry, and organized groups of patients include attempts to cure or correct abnormal color vision by the means of gene therapy, adaptive lenses, digital simulation tools, and color transformation methods. [2, 19, 26, 32, 34, 42].

the characterization of color constancy with which we began. To help motivate discussion of this problem it will be useful to be reminded of some familiar phenomena of color vision. 1.2 Phenomenology Our experience of color is not one of absolutely invariant color appearance as we view objects under changing conditions.
