Well my wheels are about to be nearly blacked out (inserts are being painted a deep flat grey Main_M did a photoshop for me look for "Holy Crap!!" In the wheels and tires section, its there) then there's gonna be a red pinstripe around each insert AND around the entire wheel.
I used yellow accents on my red mazda...looked great....red & black (most natural occuring)...red & silver (colors for my OSU Buckeyes so I had to throw that out)...red & orange (would look pretty mean IMO) ...all would go if done correctly and in moderation...good luck!
Just the engine cover for now until I get my cai then ill be able to take the stock intake out and paint it. I'm at work now but ill photoshop somethin together when I get home of roughly what I'm gonna do
