Blue is a primary color (along with green and red). It isn't a color you make, its a color you are given (but not true with all primary colors hence blue + yellow = green).

These three can be combined to make all other colors.Being a primary color means it cannot be created by mixing any BASIC colors. You can create blue if you take the yellow hue out of green though.
