Those are called sunspots. They are regions that are ca. 1200 kelvin colder than the surroundings. The resulting temperature is still very hot compared to our everyday experience, but that's what makes the spots darker than the surroundings.
Sun spots are just cooler regions of the Sun's surface, so they appear darker. A simplistic answer is that they are just a darker hue of the normal colour of the Sun. A more detailed answer is that they are all different, depending on the visual perceptual property and who the observer is - as all observers will see a different value depending on their spectral sensitivity. See the related link of a sun spot, and draw your own conclusions.
Huge streams of hot, magnetically charged gases. The sun spots are cooler parts of the surface.
No, sunspots are not white; they actually appear dark against the bright background of the sun's surface. This darkness is due to their lower temperature compared to the surrounding areas, which makes them less luminous. Sunspots are often seen as dark spots or blemishes on the sun's surface, despite being much hotter than any object on Earth.
The ancient Chinese were among the first to observe and document sunspots as early as the 4th century BCE. They noted these dark spots on the sun's surface, which appear in cycles, indicating the dynamic nature of the sun.
Sunspots are temporary dark spots on the Sun's surface caused by magnetic activity that inhibits the flow of heat. They are cooler and appear darker than the surrounding area of the Sun, indicating intense magnetic activity. Sunspots can vary in size and shape and typically last for a few days to a few weeks.

Sunspots
Dark spots that appear on the surface of the sun are called sunspots. They are areas of reduced temperature caused by interactions with the sun's magnetic field.
They are called sun spots, dark areas that are cooler than the rest of the surface.
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.
The dark spots on the Sun's surface are called Sunspots. These are formed by the sun's magnetic field because these areas have less convection underneath the sun's surface. Convection is how the sun's energy gets to the surface from the core in a circular motion. This reduces the heat in the area and makes the area appear darker than the surrounding sun. However, these spots are still extremely hot and can be many times the size of Earth!

The black spots on the photosphere of the sun are called sunspots.
A sunspot is a dark spot on the sun's surface. It is darker because it is cooler than most parts on the sun.
Dark areas on the surface of the sun are called sunspots. They appear darker because they are cooler areas compared to their surroundings due to strong magnetic activity. Sunspots are temporary phenomena that can last from days to weeks.
Galileo looked at the sun and observed dark blemishes on its surface (which are now called sunspots). From the movement of these blemishes, he was able to determine that the sun has a rotation period of about one month.
Dark spots on the Sun are called sunspots. (You knew that was coming, didn't you?)
