I was thinking of post-processing filter, too, like was mentioned before. I
don't know how possible that is though. Idea being, desaturate colors that go
beyond a certain threshold since the overall colors of the sky isn't fully one
color or the other.

Of course, that still would show a kind of colorless noise. The ideal thing
would be to duplicate nearby colors and replace the intense red, green and blue
colors with those. Yet again I don't know the limitations to such filter
creation. Just was thinking out loud.
