You are confusing the primary PIGMENT colors with primary LIGHT colors.
Pigment's primaries are, indeed, red, blue and yeller.  If you mix them all
together you get black.

Light's primaries are red(it's not actualy red but I forget what), green and 
blue.  If you mix them all together you get white.

I don't remember, but it IS a mix of the primaries. (red-green maybe) 
A lot of intro physiscs books have diagrams of the mixes of both
pigments and light.  An encyclopedia would have it as well.
