Color: (latin root celare) to conceal
" Each photo-receptor tends to inhibit the response of the one next to it. The result is that which appears to be clear appears even to be more so and vice versa. The same mechanism works for colors: when a photo-receptor from one area of the retina becomes stimulated by a color, those next to it become less sensitive to that color."
"Color is illusion, a ghost that takes life only in our visual system, when light stimulates the photo-receptors - the antennae that pick up luminous signals – that fill in the background of our eyes. The world surrounding us is sadly in reality monochrome."
