It's all what you and your corals like. Look at the Radion G5 blue. It's almost all blue leds.

It would be better in theory to use blue and violet over just blue as both are heavily used by corals. And almost no lights have UV LEDs...what they call UV is actually just regular violet. Example the OR3 UV strip is actually 410, 420 and 430 LEDs none of which are UV. Despite that the violet LEDs it uses are very good to supplement blue with.
