I don't bother to try to match. Buy what you like, buy the team jersey if you're on one. Biker shorts tend to be basic black, so when I can get some other color, I try to buy them - same for arm and knee warmers (red and navy blue).
Besides I've changed bikes three times in the past few years - started on my old college 10-speed (maroon), moved up to an Ironhorse (white with red and blue) who's frame cracked, and now ride a cherry red Specialized. Not fond of pink, especially with a red bike, BUT big brother gave me some nifty pink bikergirl duds (jersey and matching shorts), what me complain?
Oh, and my socks don't match anything either. I currently especially like my yellow and black mosquito "Bite Me" socks. Goes rather nice with the retro Rosie the Riviter jersey.
