The perception of color happens in our brain. For the vision at daylight, over our retina we have 3 different photoreceptors, which are often called red cones, blue cones and green cones. They all send signals and the brain interprets them. Thanks to the different intensity of those 3 colors every color can be perceived. On the other hand, for night vision, we have only 1 kind of photoreceptors, (called rods), and that’s why the vision is colorless. This is the biological explanation, although simplified, of course.
But the perception of color is also a psychological and personal experience, that’s why we all see colors differently, according to various factors, age for example. But also context and memories play a role. In fact, those photoreceptors are not distributed evenly, so where they are missing the brain sees what it expects to see, according to personal experiences.
So, perception of color is definitely something subjective.
In nature light creates the color. In the picture, color creates the light.”
(Readings in American Art 1900-1975, Rose Barbara (1975, page 117)
