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.
It is the international convention that the spectrum for normal references is to be divided into seven V I B G Y O R colors. A Bush man has more than 12 names for shades of green, the Escimo has more than 12 names for shades of white. But in the spectroscopy it is known that each element has its own spectral line. Thus there are as many colors as there are elements available freely in the SUN. note: More than this, should be rightfully answered by expert in Astronomy than a lay man like myself.
