Not sure what your goal is here, but I can offer a few suggestions. I have seen similar weather in Oman, when there were some storms combining rain and dust (which is not the case, granted). But all of a sudden the air would turn moist and yellow.
To capture the colour is not a problem, and you can use selection tools, or gradient tools, to adjust colour, tone curves, clarity, etc.
Now, to capture the rain squalls or showers, you need to use a fast enough shutter speed, otherwise they will just come up as a sort of fog. If as you say the rain was light, it would look almost like some fog, so not really much to do.
