Pink vs. Purple Coralline algae

I've had the green stuff on my rocks since about three weeks after the cycle. That stuff is boring.

Just recently, though, I have seen 5-6 spots of purple growing on the back wall of my tank. I am very pleased, however, I will be keeping it in check. Everything in moderation.

the dark purple stuff i have is on the tops of the rocks, it spreads about as fast as the rest of the coraline. It could just be my lights.
