I read somewhere that there are over 16 million different colors. 16 million is an estimate of how many different colors a 24 bit RGB computer monitor can simulate. This has no relevance to how many different colors the human eye can distinguish. Just as there are infinitely many numbers between 380 and 740 - including all of the fractions, of course - so there are infinitely many wavelengths between 380 and 740 nanometers - the visible spectrum of light. That doesn't even count the different tints and shades obtained by mixing in white, black, etc.
There are eight types of basic color schemes to choose from: 1  Complementary: Complementary or opposite colors from the color wheel. 2  Split Complementary: Three colorsâthe main color and colors from either side of its complement. 3  Triad: Three colors from equidistant points on the color wheel. Monochromatic: Different shades and depths of a single color. Analogous: The main color and the colors from either side of it on the color wheel. Neutral: Uses a color that has been reduced by adding black. Achromatic: No colorâjust blacks, whites and greys.
