Black wheels mean you can paint your frame any colour. The wheels will always suit the frame. Have a look for your local resparayers and see if they have a website, they should have colour samples and some pictures of completed bikes. I went for the stealth look, with everything in black, but really, just choose your favourite colour / shade and go for it. I good resprayer will also offer different finishes - metallic, gloss, matt, even glittery!
