Interesting clouds and rainbows

[Ultimate Steve]

So this is more intended as a discussion of whether or not it would be possible than an actual request, but I was listening to a rock cover of "Over the Rainbow" when it occurred to me that I've never seen rainbows in any KSP visual mod. Or, for that matter, clouds outside of layers, like puffy ones, sparse ones, or rising ones or anything like that... Or fog. But that's secondary.

Are there any visual mods that add rainbows, and if not, is the limitation just the fact that nobody has thought it was worth it?

I don’t know of any mod that adds stuff like that, but I’d certainly like it!

Since you can’t have a rainbow without rain, this would probably be a part of a complete weather mod.

A few of the planets from Galileo's Planet Pack have what looks like snow.  You can see what I am talking about in the video below that I made of a tour of Tellumo.  Go to 1:50 to about 2:05.  It does not show really well in these shots, but you get the idea. It was a really cool discovery.
