So my thinking is, I gotta have the spectrums that corals need, and for my eyes.
Corals want the blue & violet which is the 400nm range: 400-500, and to a less extent red - 600-700 (some SPS
responds well to this). Then I'd look at the spectrum analysis for the white LED
you are using, and supplement the color ranges of the corals you want to have: is it green, cyan, orange, pink, yellow? then I'd go get those colors in there as supplements.
In supplements I'd take out the whites and add two of the additional colors you want to enhance in your tank, i.e. green, yellow, etc.
from what I can see you have 26 lights.
so I'd go with 6 blue and 5 royal blues, 2 violets (for the lower end of the 400 spectrum; some apparently falsely call it UV
its not). In my thinking the violets are the lower end of the "blues" that corals absorb.
From 13 whiltes, I'd replace the followings:
2 violets (this means 4 violets in total)
7 cool whites/12k/20k
The one thing to note is that in that study I posted, they found that higher irradiance increases color in the corals, and higher growth as well (with good flow, and adequate nutrition for the growth). so you want to have as much light as possible.
