Is this Dark Matter?

If you assume the sun spots are colder than the surface how does the cold spot get to a lower energy than its environment?

(one type of sunspot)The sun spots are like a burn they reach a burn out temperature and then cool down rapidly in a shortb time or phase to be shown against the burning sun background.

The intuitive mind

Since the temperature of the corona is much hotter than the surface of the sun. I am assuming that magnetism concentrates energy from the sun into compact energetic levels above the surface. I am not saying that the dark spot is cool. I am curious though if because it is cooler than the surroundings that photographic techniques make them dark, or if there is just a lack of visible light wavelengths.

According to blackbody radiation laws the frequency of the light is the same for all areas of equal temperature. Does this mean the spots are at a reduced temperature or is something else going on and if so, what?

Observationally the spots are at a lower temperature. I imagine the spot to be like the flame on a propane torch. Where the energy is concentrated it is hot, where it is dispersed it is cooler. Magnetism causes concentrated hot areas and dispersed cool areas. Those dark spots are dark due to low emission of light in the visible spectrum. I theorize that there is still plenty of other wavelengths being emitted from that area. I would not consider them an example of blackbody radiation because of that. Also, we must consider if they are totally black or if the computer shows the major contrast to be black. I would still like to know what type of photographic technique is being used to record the image and then what type of comp processing. MV
