| In this post[1] there's a JunoCam picture from a previous flyby, which has been adjusted to be roughly as a human would see it. Still a lot of color though! This[2] paper studies the ovals but has some details on the atmosphere, including the colors: The reddish color is usually attributed to red “chromophores”, which are products of a series of complex chemical reactions, such as the UV photolization of ammonia with acetylene. These chromophores can act as coating material for the ammonia particles. The cloud structure of the Jupiter's atmosphere, and in particular the nature of vortex features, as the [Great Red Spot] and the white ovals, is still puzzling. This[3] paper tries to reproduce the reactions in the lab and compare them with the observed colors. It goes into some more details around the potential color formation. I also want to just include this picture[4] because I just love the tiny fluffy clouds, which shadows provides amazing depth feeling.
