Led colors and photosynthesis question

[FlatBrokeMedic]

what colors are vital for photosynthesis in corals. I know most led lights have some form of white, blue, royal blue, UV, violet, red, and green. I am working on a program for my radions with a starting point of the SPS AB+ program with the cool and warm whites at 100%. I was wondering how much violet effects the growth in Coral's. The violet leds in the AB+ program are at 100% and I would like to drop them to about 50% but I don't want to hurt the coral or their growth.

Thanks
