I have an undata that grows well, but is white..and has been since I set up the LEDs a few months ago. Same with a Danae. On the other end, I have a blue SPS which has been blue under 4x39 T5, 1x250 MH and 2x55 PC but is now browning. I have an couple LPS which are white at the bottom of the tank (only the ones in the middle of the tank are white, the shaded ends aren't). Norms red prostrata has a really nice red/white contrast, but the red planet looks the same (not a hint of green...white). I Also have some other SPS and LPS which are perfectly colored such as norm's bright green monti, and Rich's Tenuis, and euphylliads.
