What we normally call color is actually colored light. Color is a sensation linked to the sense of sight, which we only have when the light reaches the eye. If we can confidently say that without light there are no colors, it can also be said that we need the visual apparatus to perceive both light and colors. Our complex visual apparatus transforms light rays into chromatic sensations with their qualities of hue, brightness, intensity, saturation, etc. These qualities are associated with the memory of other sensations and in this way the organ of sight is connected with the other sense organs.
The same color causes different effects in different people because their experiences, sensitivity and intelligence are different. So it could be said that in reality color does not exist and if we had to define it we would have to say that color is light radiation, color is vibration, color is light.
