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.

If ever you needed a demonstration that so-called true colour images are not very useful for interpretation, this is it. I mean - spectra for composition data etc., fine, but cloud morphology, zonal banding, dynamics - forget it. Stretch that contrast 'til it's begging for mercy!
