Well here's the colour of my current calipers.

Been that colour for about 8 years now and the paint isn't holding up well. So any ideas? Could go red to match the car. Yellow again, but do a better job of it. Or maybe a gold if I can find some paint that will do it. Or maybe another colour?
 
My car is lucifer red with Enkie GTC01 wheels.

Black is always good

Black is dull. I want them to stand out a bit.
 
Also after replacing all the pads and disks, I now have a park brake that works.

Hah caliper covers...
i like contrast too so for a red car I would probs go green, blue or gold to contrast it.

Red or gold if black isn't an option.

Grey to be subtle or gold for the nice contrast with the red.
