An interesting new study reveals the true colors of ice giants. It appears that Neptune’s true color is a pale greenish-blue similar to that of Uranus, contrary to popular images that show it to be a much deeper shade of blue. Uranus is slightly whiter. Ultimately, Neptune has a thinner layer of haze, allowing more sunlight to reach deeper in the atmosphere. At such depth, it can be absorbed by methane gas, which soaks up red light – making the planet appear ever so slightly more blue. The presence of amassed methane ice particles may also explain why Uranus changes its color slightly during its 84-year orbit around the sun.

At least in post #1 it shows Neptune a bit bluer-green tint.
Here's an animation originally from Oxford of the seasonal change in Uranus as the color and intensity changes depending on whether we see the equator or pole. https://www.msn.com/en-us/video/animals/wat...cb56ff&ei=9 -------------------- Steve [ my home page and planetary maps page ]
