This would be a way that I haven't explored. When looking in sp, a place
to start would be the image method; it has arguments red green and blue
where you pass these bands; then it composites colour.
A similar trick should be do-able for spplot, but it's not in there, as
of now; right now you can only pass a factor and the colours to use.
