Oct 9, 2023 at 17:33 comment added Christopher James Huff There are some very potent dyes that produce colors in very low concentrations that could be produced by organisms and explain the ocean, but the atmosphere is really difficult...strongly-colored gases tend to be highly reactive, unstable, or both, and not likely to stay below white cloud cover. Does it have to be the atmosphere itself which is colored? Would, say, fog colored by spores carrying strong dye substances work? (With the side effect of surfaces tending to get coated with said substances...)
