I imagine dropping the sun's strength would help with the orangey colour a couple of you've suggested. Maybe leave it running tonight and see how it looks in the morning. I don't like to change the actual colour of my sun.
This sun is about strength '2.5' I think, maybe a strength around '1' would be cool, it isn't as if I need it high to light anything up...
Thanks for the nice comments, folks!
