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.
All colors are derived by mixing varying amounts of three primary colors: red, yellow and blue. For example, equal parts red and yellow yield orange, equal parts blue and yellow yield green, and equal parts blue and red yield purple. Adding black and white to the mix yields an infinite amount of shades and tints. In the hexadecimal notation system, as described by ColorHexa, each color is given an alphanumeric code for identification. The hexidecimal code for burgundy is #800020, and the hexidecimal code for maroon is #800000.
