You can make it any color you want, if you have a #0 Phillips head and know how to do a good job of spray painting. I opened mine up in just a few minutes, just unscrew the 4 Phillips head screws, then carefully pry open the case near the four snaps (2 up front between the thumbsticks, one each on the sides about an inch foward of the shoulder buttons, then the tricky bit; push the bottom of the case past the L2 and R2 triggers at the same time (doing one side is easy, but then makes the other side hard to do). The rest is easy, just detach the long ribbon cable from the circuit board, unplug and remove the battery, then unscrew the lone screw under the battery tray, and detach the ribbon cable for the touchpad from the circuit board. The rest comes out pretty easy (you will have to remove the light bar and micro-usb Jack from the back if you want to paint it too, but the grippy texture may not be the same if you paint it, maybe one or two light coats will be OK).
Before painting, mask off any of the labels on the case you don't want covered by paint, and remove or mask the sticker on the back if you paint the back too. Gonna paint the front of my 2nd controller a nice metallic blue.
