Is this blue and green coralline algea?

[Zoa_Fanatic]

I have regular purple coralline growing on my rocks. I also have this very light blue colored algea that looks similar and a hard green algea on some of my other rocks. Are these coralline? Also some white colored areas on my back wall. Is that the start of coralline?

Also have some red coralline growing on the front rocks in the second picture.

It may be blue. Hard to tell from the pics.
I have some red also.
If the red is slimey to the touch and does not blow off it may be red turf algae.
I have urchins that are putting a heavy dent in the red turf but they also eat coralline.

i have red slime in there too. This is definitely red hard coralline. Let me take some better pics.
