Is this rhodactis getting too much light

[ZzyzxRiver]

Under dim lights and in blues, my rhodactis is a beautiful vivid green. During the day it’s a barely green brown color (it’s actually less green than it appears in the photo). Is that normal, or is it stressed somehow?

Should be in low flow and 50 to 75 par. I keep mine in partial shade to.
