I was just going to get a whole stack of white LED's, and then enough coloured LED's to match all the colours of the inserts. That way I could chop and change as I like. I really want the greens, reds and yellows to 'pop'! But, at the same time, I want to keep them their natural colour. I saw some pics on Highend where the greens have actually taken on a blue-ish tinge. I dont really want that, its a traffic light colour, so they're supposed to be green.
