You could use a CAT4101 based driver and simply add a few more red leds to make up for the difference in forward voltages. The Cat4101 is rated to drive strings of leds up to 25 volts. With that knowledge, you could drive 6-7 "white", "cyan" or "violet leds per string. The "red" would require at least 8 per string to keep all the Cat4101's happy with a low voltage drop.
You could power your lighting system with a Meanwell 24 volt 6.5 amp supply. They're available for cheap on FleaBay.
