Lime Green and purple on Rocks only

[Ronnie Burda]

I have this lime green and purple algae growing on my rocks only. Is it possible that it is the start of coralline algae? I couldn't blow it off with a turkey baster so tried scrubbing it off with a toothbrush. No luck getting it to come off. Thanks in advance for the help.

You’re correct both green and purple coralline algae.
Is the last pic your tank ? I see hair and bubble algae
