It's not the movement or even the bands that I was questioning. To that extent, equivalent examples can be seen all over the solar system. The earth itself has convective bands corresponding to equatorial, temperate and polar weather systems, if I recall correctly. It's the lack of mixing of colours that confused me - there needs to be some form of continuous generation and destruction of those colours in order to keep them separate.
By way of example, say you could dye an entire tropical cyclone on earth pink. I don't think anyone really thinks that in 2 years there would still be distinct 'pink systems' in our atmosphere.
The upwelling jets in the example above makes sense to me in terms of supplying fresh phosphor (or whatever chemicals) to the surface, which then subsides due to convection before it has a chance to mix to uniformity.
I'll attach the sort of image that made me start thinking about all this.
Best,
