I've noticed on multiple occasions, that after heavy rainfall, the sun appears a pure glistening white, even if it's already standing low in the sky. I can't discount psycho-visual effects as an explanation, such as cloud shadows from above affecting color perception. Yet considering the many warm cloudy sunrises/sets I've seen, I'd be surprised if that's all there is to it.
Is anyone familiar with what I'm describing and knows of a scientific description of the phenomenon?
Edit: I've gathered a few images which I think show what I'm seeing sometimes: http://imgur.com/a/evENm
