Algae ID - any help appreciated

[Tomsk7]

New tank, started with dry Rock & Dr. Tim's. I dosed pink & purple coralinne that I got fresh from Algae Barn about a week ago.

1) per instructions, I wasn't expecting anything for several weeks.
2) this looks more brown/yellow/slightly red than pink/purple.

So, cynobacteria? Fast starting Coralinne? Something else entirety?
