crimson is usually the coralline color, and its very thin. red is the cyano color, and its soft, sometimes slimy & thick.

If you point a powerhead at the rock, does the red blow off? Or does it stay in place? Cyanobacteria - while it can appear red, blackish, green and purple - does not really adhere to the substrate. It spreads over it like cobwebs.
If you can get it off the rock with just a little water movement, its cyano. If it stays in place it may be a coralline algae, but there are some types of foraminiferans that show up as nubby red spots on LR. Someone else who really knows foram's can help you out on this.

I think I know the answer to this, but I'm not 100% sure so I'm going to watch and learn.

Different type of coralline causes that variation in colors and such I assume. I have some deep deep red colored coralline that appears to have a different thickness (thicker) than the purple coralline.. also the purple stuff just seems to sprout up places, this red stuff seems to like it with a little less light and spreads slowly... but from the original spot.. as in it doesn't pop up around the tank that I've noticed.

The different colors are different species, and the different coloration may help them to take advantage of the various depths/lighting levels at which they are found. So I believe its mostly a light factor, but a pink caoraline isnt going to to turn red beacause the lighting changed, The red is just going to outcompete and grow over the pink.
Here's what I notice in my tanks
Green coraline - low light, generally a first colonizer
Red Coraline - low light
Purple coraline - Variable lighting, but generally moderate
Pink coraline - High light, or high K, seems to prefer smooth surfaces like tank walls for some reason.
The greens and reds dont usually stick around long and are easily outcompeted by pinks and purples at least under the conditions we generally keep in our tanks.
Lighting color, or Kelvin may also play a role here.
Greens and reds seem to prefer lower K, and pinks and purples seem to prefer higher K, but this kinda goes back to light intensity.

The pinks and purples also seem to take alittle longer to develop, once they become established you'll have trouble keeping the glass clear.

I've thought that what I had was red slime algae but now that I read this I'm thinking it may just be red coralline algae? When I put a power head on it, nothing happens...
