Microbial geneticists from the University of Maryland say that ancient microbes used not chlorophyll to absorb sunlight but another molecule called retinal. They absorbed the green part of the spectrum, reflecting the red and blue ones, which resulted in purple.
This theory is additionally supported by the fact that the sun transfers most of its energy in the green part of the visible spectrum, while chlorophyll mostly absorbs blue and red waves. There’s also a supposition that the balance may shift again one day: the Earth will once more become purple, while looking green from space due to atmospheric changes.
