The color we perceive depends on the mixture of light wavelengths and brightness entering our eyes, but it is complicated by the way the light detectors in the eye work. Yellow is a pure color, but because of the way the eye works a mixture of red light and green light looks yellow to us.
Any color can be created by mixing the correct proportions of red, green, and blue light. This is the additive color system, with white (shades of gray) being equal red, green, and blue. This is the way television and computer screens work.
Colors can also be made by selectively filtering (subtracting) colors from white light. Cyan pigment (your blue above) subtracts red and yellow pigment subtracts blue, so only green is left. This is the subtractive color system. This is the way printed media show color.
As usual, wikipedia has a good article:
