Paint them. You can get caliper paint from Halfrauds. The rough finish on the calipers will be a pain to get vinyl to stick to.
If you ensure that everything has been properly cleaned and prepped before you paint them, and that you give the paint a decent amount of time to dry, its pretty chip and scratch resistant stuff.
I did the calipers on my last car, as they were very visible through the alloys I'd fitted, and including prep time and drying time, the car was up on axle stands for a weekend.
When done properly, it looks quite good, when done badly, it looks terrible!
