Sunspots aren't actually dark, if you could look just at a sunspot it would still be bright enough to damage your eyes. They are however, significantly darker than the surrounding Sun, which makes them appear black. Sunspots are darker than the surrounding Sun because they are cooler areas.
What happens is a "tangle" of magnetic field stops the convection bringing new hot plasma to the surface, meaning the area inside the tangle keeps cooling, we can't see magnetic field lines, so what we see is the cooler region of plasma.

An area seen as dark spot on the photosphere of sun?
A "sunspot."
Why is the center of a Sunspot dark?
It is not actually dark, it is just dark in comparison to the rest of the Sun's photosphere. This is because the magnetic fields/flux associated with the sunspot inhibit convection and therefore reduce the amount of heat rising from below where they are present.
How do you use the word sunspot in a sentence?
You should never look directly at the Sun to try to see a sunspot, as they are not as dark as they look in photographs. The magnetic disturbance that causes a sunspot will seldom occur in the same location twice.
What is the light colored region around the dark center of a sunspot called?
Penumbra
Why does a sun spot appear dark?
Well, a sunspot is not really dark but it is at a lower temperature than the surrounding gases on the surface of the Sun. So it only looks dark by contrast with the area round it.
