Why are non-gray colors used when rendering gray letters?

Why is the left of these better than the right? Is it called something?

See Why does anti-aliasing in black characters use colors other than gray-scale? on the GraphicDesign site.

Words to look up are "anti-aliasing" and "sub-pixel rendering":

[Subpixel rendering] takes advantage of the fact that each pixel on a colour LCD is actually composed of individual red, green, and blue or other color subpixels to anti-alias text with greater detail or to increase the resolution of all image types on layouts which are specifically designed to be compatible with subpixel rendering.
