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.
You might also say 216 as while there are 256 colours in the web-safe palette, operating systems reserved some of the colours for their own use resulting in 216. This number is also easily divisible by 6 and so allows for 6 different shades of red, green and blue to create one colour.
