All plants have chlorophyll-a which blocks(reflects) green light and absorbs red and blue wavelengths. It seems like it would be more efficient for plants to absorb green light since energy is most powerful from the sun through green wavelengths. However, the chlorophyll-a in chloroplasts actually defend the plant from harmful damage of the TREMENDOUS amount of power from the sun transmitted in green wavelengths.
SO CHLOROPHYLL-A PROTECTS PLANTS FROM TOO MUCH ENERGY IN GREEN LIGHT.
Algae is more simple than plants
Sunspots appear dark (in visible light) because they are much cooler than the rest of the surface of the Sun. However, even though they appear dark, they are still very hot.
Mediterranean is the answer
