I would just clear thte jewel with toothpaste, then add 6 red led's around it on the inside of your XBOX case/lid. This will look much better than having red paint on the back of your jewel. Here's a photo of my XBOX from a while ago with the red led's on. (I have two sets, green and red, controlled by a switch). In this photo, my xbox jewel only has 4 led's per colour, so if you do 6 led's, it will look much better.
