coraline algae colors?

[multicincta]

I know they come in a variety of colors, but it seems I have some yellow showing up. I know, pictures, right? I'll see about getting some up on this thread ASAP. In the mean time, does it come in yellow?

All kinds main... It just depends on the lighting, parameters, stocking levels etc. "Yellow" does sound like a sponge though.

Could be the green coming in. I'd believe that could look yellow-ish at first under right lights.
