Sadly this doesn't work, photons don't have any mass otherwise they 
wouldn't be able to travel at the speed of light.

Different colours do however have different perceptual weights as I 
demonstrated in research published as:

Balance in pictures. I.C. McManus, D. Edmondson and J. Rodger
British Journal of Psychology (1985), 76, 311-324

To save you looking it up the perceptual weights of the colours produced 
bt the separate RGB phosphors came out as Red heavier than Blue heavier 
than Green.

The real relevance of this paper to the Sprint world is that it suggests 
why the RS has the big silver RS stickers. If you paint out the stickers 
on a picture of an RS it gives you a large block of solid colour which 
tends to make the bike look front heavy. If you put it next to an 
unmodified picture the modified fairing looks like it comes down a few 
inches lower.
