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 no certain answer of how many colors are there in the world.Careful measurements of our visual systemâs best performance have been made by psychophysicists . They have shown that we can see about 1000 levels of light-dark, 100 levels of red-green, and 100 levels of yellow-blue for a single viewing condition in a laboratory. This means that the total number of colors we can see is about 1000 x 100 x 100 = 10,000,000 (10 million). A computer displays about 16.8 million colors to create fullcolor pictures, really more than necessary for most situations. However, the answer is not quite so simple.
