I'm not sure what prompted this (although I can guess), but I do have some dull pictures to contribute.

(The one with the fir trees and the rainbow is one my favourite screenshots, but I can see that some people would probably consider it genuinely dull: the colours are so desaturated it's almost black and white. But the real world can also look like that during rain and fog, and I love the fact that the game sometimes has days like that!)
