it'll be pretty hard, and you can screw up pretty easily. the green color is created by blue paint on the gauges themselves + yellow light bulbs. if you want a red color, you'll have to remove the blue paint, and replace the bulbs with some kind of red lighting souce. if you *really* want to try to do it, i can tell you all that i know. i've been working on making the A/C controls white, but haven't had time to finish them yet.
