The idea of using non-RGB filters is sound and a number of CCD sensors
have used filters more like C, Y and M. Why RGB is used on digital
cameras I am not sure.

My guess is that to do otherwise would increase the chroma noise too
much. Chroma noise in digital cameras at high ISO is already
intrusive, and anything that increases it may be unwelcome, even if
sensitivity improved. Without direct experimental data it's hard to
say.
