Paint and light have diffrent sets of primary colors. In light it is Red, Green, Blue. Computers use these three colors for everything too.

In astronomy we use red, green, and blue filters in separate exposures to produce a color image, because our CCDs don't have dedicated color pixels, unlike the CCDs in most digital cameras. This makes the CCD more sensitive, which we consider more important than easy color photos.
