Hello. I have a 75g tank with a Nova extreme pro t5 fixture with bulb type and arangement as follows.

The tank has been up and running very well for 10 months with alk=9dkh, calcium=420 and ph=8.2 these params stay pretty consistant. I get no nitrate reading and zero phosphate and run skimmer and cheato in sump. My question is some of my corals are very light in pigmentation. For example my kenya tree which I have had since the start of this tank and prior is very light pink and not a brown color like when I first recieved it. Also I have a very larg colony of anthelia that is also very light pink to white and the same with a devils hand coral which is a very light color also. All of these corals were quite a bit darker when I received them. They are all multiplying like crazy and otherwise look very healthy but trying to figure out why the difference in color. I have a friend that has the same corals that I gave him and he also gave me that are very much darker in his tank. He uses MH plus VHO for lighting. I also run carbon and gfo 24/7. Should I have any concerns of is this just a product of my lighting.
Thanks for your time.
