Consider I have a few references from white to yellowish, and I look at them in 2 different lights: a cool-coloured light (white/~6500k) and a warm-coloured light (yellow/~3500k). Firstly, intuitively, I thought that I will perceive the whiter ones to be yellower in yellow light, but I don't -- in fact, it's the opposite: I see the yellower ones whiter in yellow light.What does it mean? Does it mean that the colour constancy mechanisms of humans notices there's a yellow light and tries to adjust the brain such that I perceive yellowish stuff as white? If so, how come the ones that are intrinsically yellowish are still perceived as white? Does the colour constancy mechanism overestimates how much to correct?
Does color constancy overestimate?
