I think there should be a way of actually changing the look of the area on a celestial surface during an eclipse. Normally on Kerbin, during a solar eclipse, the ground you are on still feels like daytime, but in real life it looks like dusk. There should also be lunar eclipses, when Kerbin passes in front of the Mun and sun, and the Mun would turn red. Realistically, any other body in KSP should have this event if the sizes and distances are correct, and possibly varying effects on the planets. Just a suggestion that would be a cool and realistic feeling to KSP. In that image, the vehicle and the ground area that should have been shadowed are still bright as normal. Theoretically, the same thing should happen as when orbiting vehicles are on the night side of planets... they go dark. This should happen as well with the surfaces of planetary bodies (in select areas) and vehicles in those areas.
