I went with about 2:1 royal blue to neutral white and to color is gorgeous. After only 2 weeks it's still too early to say anything about algae growth, but I believe corals also need red spectrum.

Looking at the attached flux distribution for the XM-L's I would say there is no need for any additional green lighting. Red... well maybe, but that might encourage algae growth. I think I'll try out my setup for a while. The only mods I am considering right now is optics and some more royal blues for better actinic lighting and a cooler (K) look
Edit: Looking at the XP-E Cool Whites, there seems to be slightly more green content in the XM-L cool whites
