Paint's a good choice.
Posting that Reddit choice about using covers? Bad idea.
Heat from friction in the pads and the stuff around them has nowhere to go except into the hydraulic fluid and piston.
Brake covers are never a good idea.
Look and actual functionality are two different things.
This covers are also designed poor without taking into account cooling effect.
Have them professionally done by applying paint if color is something you want to accomplish.
