Chlorophyll just absorbs blue and red light; it hardly absorbs any green light at all, so the green gets reflected back to our eyes, which is why leaves appear green. Other pigments that plants have in their leaves absorb light of different colors, so they reflect red, orange, yellow, or blue light and appear to be those colors to our eyes.
Ponds contain a rich diversity of microbes. The green microbes growing closest to the top are green algae and cyanobacteria. This green color comes from chlorophyll, a chemical that turns solar energy into food that the microbes can use. The conversion of light into chemical energy is called photosynthesis.
