Question

Write note on perception of colour.​

Answer 1

Answer:

The perception of color is formed in our brain by the superposition of the neural signals from three different kinds of photoreceptors which are distributed over the human eye's retina. These photoreceptors are called cones and are responsible for photopic vision under daylight conditions.

HOPE THAT THIS HELPS YOU.

Answer 2

Answer:

When a person views an opaque coloured object, it is only the light reflected from the object that can activate the visual process in the eye and brain. Because different illuminants have different spectral energy distributions, as shown in the figure, a given object in these illuminations will reflect different energy distributions. Yet the eye and brain are such superb systems that they are able to compensate for such differences, and normal-appearing colours are perceived, a phenomenon called colour constancy.
