All in all, the sunspots appear dark because the are darker than the surrounding surface. They're darker because they are cooler, and they're cooler because of the intense magnetic fields in them. share | improve this answer.
The Photosphere and Sunspots. The visible glowing surface of the sun is more appropriately called the photosphere, and it has a darker edge, called a 'limb.' It's darker because the temperature in the sun's photosphere decreases outward.either the photosphere nor the interior of the sun is solid-it's gaseous instead. A sunspot is a relatively dark spot on the sun with a lower temperature than the other parts of the photosphere. Sunspots occur in places where the magnetic field in the photosphere is many times stronger than average.
