Translucent greens and browns for plastics, and translucent baitfish colors for hard baits. Thats just my .02, I know guys who catch plenty of fish on outlandish colors in clear water. If the fish are biting, color is the least concern, IMHO the most important thing in clear water is not color but to NOT be seen an/or spook the fish, thats the real challange of clear water. If you can see them in 25 fow, guess what...............they can see you too. Clouds and wind are your best friend in those situations, as is heavy cover, or something that blocks the fish from seeing you.
