What Causes the Vibrant Cloud Colors on Jupiter?

[mrjeffy321]

When you look at a picture of Jupiter,
[Like this one for instance: http://www.calpoly.edu/~rechols/astro101/astro101pics/Lab4pics/jupiter.jpg" ] one thing you notice is all the different colors of clouds it has.
We know that Jupiter also has some pretty strong storms with extremely fast winds too, blowing everything around and mixing up its atmosphere. Why after millions of years and all that wind mixing it up has it not all blended together?

You're discussing a dynamic system subject to heat flow from the interior, solar radiation at the cloud tops, and a dozen (plus) lunar tides; therefore, don't expect an equilibrium state.
