algae ID please

[christyf5]

Does this algae blow off the rock when you use a turkey baster on it (or a powerhead or something?).

It looks to me like some really wild colors of coralline algae, I find your photo is a bit dark (and small) for a really good ID though. Can you take another shot of it in a different area (one that isn't so convoluted? ie. flatter area?).

I enlarged your photo and lightened it some, its still kind of hard to tell. I still vote for the purple stuff as coralline but I'd keep an eye on the green, it looks like a green coralline to me but you never know, sometimes it can be tricky.
