I don't think that's necessarily true. I have chrome/ion projectors and mine don't shine yellow. I also had a set of Catz that were ion and they didn't shine yellow either. I'm running a set of Hyper 55W bulbs in my projectors now and they're not yellow.

As for painting them, I think you should leave them black. My buddy and I just put a set of them on his '99 and they look sweet flat black. You said you're going to leave your lip black and I think they'd match that very well. :naughty:
