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.
Here, each color is 8 bits, for a total of 24 bits. Since each color has 256 shades, we can multiply 256 for red, times 256 for green, times 256 for blue and get millions of colors, (256 x 256 x 256 = 16,777,216). Millions of colors are pretty much whatâs accepted for a monitorâs colors to look âtrueâ to the human eye.
