Bug Description

Original request: https://sourceforge.net/p/stellarium/discussion/278769/thread/091c6569/

When the Moon is rising over the horizon it gets a beautiful red hue. Goes into yellow, and then into white when the Moon's high enough in the sky. Stellarium should simulate the beauty of a Moonrise/Moonset.
The picture below shows what I'm trying to tell.

It would require changing extinction to not use one value for magnitude loss, but three (R/G/B), and here also some accounting for atmospheric dustiness. Is there a model available?

R/M are of course the full answers. But likely a simple "reddening" model may suffice. Just how much mag shall be removed in R/G/B? (Just some empirical hand-crafted formula or some scientific backing by dependable physical measurements/models?) Next thing then will be differential refraction...
