The concept of color constancy can be easily understood in terms of photography. Our eyes ability to see color constancy refers to the fact that cameras are unable to interpret different types of colors in different types of light. Because of this technological limitation, cameras must have a wh...
Although surrounding colors can profoundly influence the appearance of a test color in the laboratory situation, these effects are seldom obvious in natural environments and probably represent an influence of the same processes responsible for color constancy. This concept refers to the fact that colors...
Shading and antialiasing operations need to occur on linear light values – values that are proportional to physical light intensity. Other operations that require linear values include resizing, alpha compositing, and filtering. Rendered buffers are written out as HDR values and later used to generat...
“belonging” is most apparent when nonluminous objects are viewed. It is due to the fact that in daily life we look at many objects simultaneously, subconsciously comparing their colors or comparing color sensations from differently colored or differently illuminated parts of the objects. The color...
Color visionis the ability to distinguish and identify lights and objects on the basis of their spectral properties. This entry presents several topics that underlie current theories of human color vision. These are trichromacy, opponency, adaptation, and color constancy. To understand the key ideas...

It's worth considering the fact that traditional easel painters, because of their historically limited palettes, rendered colors with gamut limitations that are easily as extreme as many types of color deficiency. However, 20th century painting styles have created and provided justification for ...
According to [8], color consistency or color correction is still an ongoing research due to the fact that no general method can be used to correct all images in most general cases. This statement is also supported by [7], [9], [10], [11], [12], [13]. There are several methods ...

“Color constancy” is an example of subjective constancy and a feature of the human color perception system which ensures that the perceived color of objects remains relatively constant under varying illumination conditions. A green apple for instance looks green to us at midday, when the main ill...
