Lobo and scollys lost color

[kac01]

I have a 180. Running three Radions at 35 percent. Lobos have been in various spots from bottom to top. Scollys always on bottom. They have faded in color. More brown than bleaching out. Most the corals are doing great. Will colors come back? If so how do I achieve that. Thanks
