Eve is a very, very purple planet. How? What's in the oceans, the soil, the atmosphere that makes it so, so purple? what kinds of liquids or gases or elements or compounds could possible make a planet so purple? I've heard it could be ammonia methane, or argon, or iodine, or maybe a combination of very red and very blue compounds. would any of these fully explain though why it is so, so, so purple?
