Here is an interesting thing: (Please read slowly and carefully)
You always know about how to distinguish color from black and white, of course. But why?? This is because black (0 0 0) and white (255 255 255) are 2 of only 6 colors that all colors are based on, the others are red (255 0 128,) yellow (255 255 0,) green (0 255 128,) and blue (0 0 255.) These 6 colors are the psychological primary colors. (Look up primary colors at http://dictionary.reference.com if you want to see how they are used.) This set of colors is much less well-known than the traditional primary colors (red, yellow, and blue) or the light primary colors (red, green, and blue,) and was first identified in 1874 by a theory called the opponent color theory. All colors can be thought of as being on 3 scales, the "black-white" scale, the "blue-yellow" scale, and the "red-green" scale. This explains why some colors can be mixed to form new colors, but certain pairs "cannot" (actually, they can; the mixture is just gray.) Colors that produce gray when mixed are called complementary colors. Black and white are complements, as are red and green, as well as blue and yellow. I've been wondering if anyone can soon be creative and make some pictures entirely in either blue and yellow or red and green. Please note the following rules:
For making pictures in blue and yellow, the colors you use are the exact same blue and yellow that most people familiar with RGB think of: 255 255 0 for yellow and 0 0 255 for blue.
For making pictures in red and green, you must use colors that are slightly less yellow than the "red" and "green" that most people familiar with RGB think of: 255 0 128 for red and 0 255 128 for green. The colors that are used as "red" and "green" are actually somewhat orange-ish and lime-ish.
