Maybe black with flames? Or Diamond-Plate? Hmmm... Me thinks this could become much more complex later on.
Wow. Our minds seem to work alike pretty frequently.
The flames would be easy to do, but diamond plate is kind of thick to be able to easily follow the curve of the cans.
Did you think about blue/silver lightning on black yet?
....How'd....How'd you know?
And for the diamond plate, I mean faux painting it. Obviously not me, cuz I don't have that skill. CustomNESdude might, though.
