blue, i have a 3 or 4 year old clarion cd player in there now. matches perfectly, day or night. the stuff is out there, you just have to look. i think even the newer alpine models would look stock, some of them can change the color of their buttons to match the rest of the dash. another option is to buy a sweet cd player, and then change the lights in your car to match. you have to admit, blue illumination is soo much cooler than green.
