Red-green-blue. The three primary colours in additive colour theory. When the three colours are combined (added together) the result is pure white light.
RGB is a common colour theory used on computer systems - each of the three colours are assigned their own colour channel which can be manipulated independently. 24-bit RGB assigns 8-bit channels to each of the three colours.
cf. additive colour, bit depth, CMYK, HLS, HSV.
