A little while ago I caught some clouds back lit during a sunset. A wall of cloud reflected the orange to red rays of the setting sun back to the observer positioned to the west. The clouds inbetween had a different blue grey about them. Well, you can see the pics below and have a better idea than what my words will take you to.
