You can't go wrong with metallics! Depending on your skin tone, silver, pewter, gold or bronze will work. Or if you are brave, a bright color could work: yellow, red, green, etc. Or a neutral -- bone, tan, etc.
Basically, anything except black or trying to match the blue will be perfect. (And you could get away with black or navy if you really wanted to, but they're trickier and won't be nearly as attractive as a metallic or a color.
