Hi All,
I shoot pictures, do have any idea what’s that? the red on the rock is growing a week ago. And the green is nice and turning to dark, the question that withe spots, is not the dry rock colour. When the light turn to blue more visible. Do i need worry about it?

The red looks like cyanobacteria. White and green *might* be coralline.
