I keep 2 x 10k MH, 2 x 36w Giesman True Actinic, 4 x 10k 22w T5, 12 x 3w Blue LEDs. Lots of things in my tank are starting to switch a more vibrant color including a wicked blue/purple Acro. I doubt it is as maxed out as the lighting in those pictures though.
I am going to install another 18 5w LEDs soon including 9 in the purple spectrum and 9 in the blue. This should help bring out the colors.
