The black spots on the photosphere of the sun are called sunspots.
We call them sunspots, but dark and cool are relative terms. A sunspot is dark only relative to the surrounding solar surface, but still intensely bright compared to your common household light bulb. It's cooler than the surrounding solar material, but still hot enough to vaporize a spaceship and anyone inside it in a fraction of a second.
