Chlorophyll is primarily green in color. It is the pigment responsible for the green hues in plants, algae, and cyanobacteria, playing a crucial role in photosynthesis. Chlorophyll absorbs light most efficiently in the blue and red wavelengths but reflects green light, which is why it appears green to our eyes. This pigment is vital for converting sunlight into chemical energy, enabling plants to synthesize food and produce oxygen as a byproduct. Its abundance in plants significantly contributes to the overall color and aesthetics of the natural environment.
