SPS experts, the color of SPS require a certain light intesisty?

My red planet is mostly red. Hard to tell if it's my high phosphate or the high light. It's in very intense Radium light. Now I want to frag my pearlberry and try it with less light.

The Red Planet gets more green in it and less red the more you move it away from the light.

Red Planet
High light = deep red with red polyps
Med light= greener base with red polyps
