Color Appearance Models are even more in the realm of the subjective
phenomenological experience of color than CIE XYZ / CIE Lab - and less
useful in an attempt at absolutely defining/describing a color outside
the context/scene where it is experiences/observed. With a color
appearance model the squares A and B in the Checker Shadow Illusion (
https://en.wikipedia.org/wiki/Checker_shadow_illusion ) would have
different colors - since they *appear* to have different colors.
Through color constancy this affects not only the apparent luminanace
but also the apparent hue of colors in a scene.
