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.
This activity shows two different ways you can mix colors together to form a new color. The first way of mixing colors uses different colors of light. When we mix color this way, the more light we add, the brighter the combined color gets. By mixing just three colors of light, Red, Green and Blue, we can make any color we want. These are the primary colors we use to make the millions of different colors we see on TV and computer screens.
