Blue LEDs will bring some colours out of acans but blue plus t5 are supposedly to bring the best colours out of acans, in the ocean I would suspect acans are found quite deep down meaning that the light they receive is most likely going to be a light to dark blue and very muted.... something to keep in mind, while leds don't seem very bright to the eye they can and will bleach a lot of lps, even some Montipora species get effected by them if not acclimated properly.
