I'll try and get a shot this week... I have about a 4" colony baking under a 400 wt radium halide. I have frags of it all over the tank and you do have to move it around to find that sweet spot. The colony is mostly red/pink with a hint of orange. Frags in lower light are orangeish with a blue encrusting base. In ideal light you should see pink/red/orange with the blue encrusting growth ring. I think it grows fastest under high flow and light though...
Awesome way to find out where stuff looks the best. I often make small frags of my favorite stuff and move them around too and see how they look in different places. And you can have a nice encrusted frag to sell later. win/win!
