define in more detail your colors not looking too good.
If you mean they are washed out/possibly bleached some, I would suggest putting all of your rics low in the tank and off to the side, as far away from your lights as you can get them for a while. Either that or lift your lights some if possible or BOTH.
While they can take and thrive in quite a bit of light if acclimated to it slowly, depending on how you have things set up you could possibly have very easily have fried them a little with the set up you described. If thats the case, they can and will come back. It will just take a little time
