A sunny day has visible sun rays. If you try applying a yellow color fog as atmosphere, it will look good close up but turn into a cartoon in distances past ~256-384 map units.
I would like to limit the intensity of the fog over distance. I think I've requested this before
I just don't want the fog to eventually fade into a solid color
Third picture is an exaggerated illustration. It looks good close-up on the palm trees but then it goes into cartoon-mode.
