Purple earth hypothesis suggests that early photosynthesis wasn't chlorophil based, but on a simpler molecule (retinal) which is purple colored. The Canfield ocean was supposed to have followed this time yielding a turquoise life, where the ocean was anoxic and sulfidic. That was then replaced during the great oxigenation event which lead to the current green earth.
