Could you have seen a player with a blue face and red lighted buttons? IIRC there is such a picture about somewhere, probably from Tony Fabris...
The lighted button hack also improves the effect of the neon lense.

I actually managed to get my red neon lens to display blue text with one of Darkstorms gels. It didn't photograph well, but I did attach two pictures. I can't wait to get some lighted buttons to go with it. It is much more visible than in the pictures, but still doesn't match the dash exactly.
