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.
The twelve hues of the color wheel are divided into primary colors, secondary colors and tertiary colors. Primary colors: There are three primary colors. They are the hues yellow, blue and red. These three colors are the hues that in theory can be mixed to make all other colors. If you mix the three primary colors, in theory it would produce black. Secondary colors: By mixing two primary hues together you create a secondary color. There are three secondary colors. They are the hues green, violet (purple) and orange. Orange from mixing red and yellow, violet (purple) from blue and red, and green from yellow and blue. Tertiary colors: The third set of hues are known as tertiary or intermediate colors. These hues are made by mixing adjacent primary and secondary hues.
