they aren't green. . .

Okay, so I have some gsp that is at the bottom of the tank on its own island so it doesn't take over my rocks, but it is only marginally different coloured than the purple variety I also have. Is it just a light thing that won't be any different until I let it have a spot where it may take over(aka near the lights) or will it eventually become green again?

Did it used to be green? I have brown star pylops, and blond star pylops too.

They were a frag from a green mat, so I'd hope they were green
