Relief background advice

Hello Orchidians: I’ve been designing a pair of cuff bracelets with
high relief images. The customer wants the background to be a dark
aqua color similar to tropical water. What is the best tried and true
application that I can use create this effect and will stand up to a
bit of bending and wear/tear?
