Autotrophs are organisms which use pigments for photosynthesis by absorbing light at specific wavelengths. The dominant chlorophyll-a absorbs in the violet-blue (430nm) and red (660nm) wavelengths, but not green, which is why is green. Phycocyanin, an accessory in , absorbs in those green wavelengths, so is blue in colour. This is why we can determine algae types from space.
