#13Why is Jupiter so colorful? If the variation of color are indicative of a similar variation in density, why is there so much turbulence in Jupiter, why are the upper layers not more consistent? Tidal motion? Anyone know?
It says exaggerated color/contrast. It seems to be a trend lately like the recent images of the Moon and Pluto. They might even be translating non-visible spectra to color so the material composition can be distinguished better, like they do with nebula and such.
It is well intentioned, it makes the images much more informative, and they are just really cool, which helps with public support. But it is also a bit misleading and confuses people.

#15It's so scary! All those swirls are like planet size hurricanes. Had Jupiter been bigger, it would have been a star, and life on earth would not have existed. Gives me chills.
Jupiter would need to weigh 13 times its current mass to become a brown dwarf, and about 83 to 85 times its mass to become a low-mass star [1]

Also interesting to note that the combined mass of all planets in the solar system is only about 1.4 Jupiter masses (or 0.0014 Solar masses). The Sun did not leave us much to work with if we’re hoping to build a second star!

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.

Not sure a small star (e.g red-dwarf size) in Jupiter’s orbit would make much difference to Earth, other than it being brighter at night when it’s in the sky.
