Humans perceive color when light enters the eye and is detected by the photoreceptors, called cones, which are mainly located in the fovea. We have trichromatic color vision which means we have three different kinds of cones that detect a specific wavelength of light, namely short (blue), medium (green), and long (red). How we perceive color also depends on how dim or bright the light is. . Color Schemes, Use of color in Interior Decoration . We all live in a world where color is a part of us. Color in everyday life is very diverse. It gives us pleasure, increase our appetite and provide us serenity. Color is a mental phenomenon which is evoked by light striking the back of the eyes..
