Just colored the leds under the keys. Fairly simple process. If you decide to do this, wear gloves! If you don't, there will likely be some ugly fingerprints on your screen. Follow the instructions on the disassembly faq and then just color the leds the same way as the one under the pearl. Works great. I would post pictures, but the only camera I have is my pearl. It turns the keys a slight blue. I almost want to say it's not as noticeably blue as the pearl is.
Anyway if your going to do this, be careful, go slow, keep everything in order, and wear gloves. Also, if u don't have a T6 screwdriver, then you might be able to use a small eyeglass screwdriver to fit in the screws. or, you can go buy a torx screwdriver for about $10 at Home Depot or similar. (a torx screwdriver has 6 points on it as opposed to a philips head which has 4. hope that makes sense.)
If you're up to it, it's well worth it.
