With your green, the darker red is a best match to me. Flashy and stands out without contrasting so much that it's all you see. My 2¢ anyway . . .

 

The second pic gets my vote. It will definitely look good on your black rims.

 

darker red in my opinion, i wouldn't go red on a green vehicle personally though

 

I personally would get the car color on the caliper, something along these lines.

 

red on green = chirstmas!

the dark maroon looks best, or black.

 

I've done many colors though the years and from now on I'm sticking with black - clean looking and if the coating/paint ever chips/fades/etc its easy to repair and have it blend in as well as having road grime blend right in.

 

I like the brighter red. It really catches the eye.

 

if its out of the three. i like the last one...but prefer black or green on your color.

 

I saw a GTR the other day, and they had copper colored calipers. They looked beautiful.

But, if its the 3, I'd say the dark red.
