Mineral Mist is the colour I have in the little bedroom Bunnyflop! That is the blue I like - and because it is so pale, it looks lovely wiht almost totally white bedding etc
It's a beautiful colour - the colour of heaven (IMHO 
). Very pale and pretty and delicate. The blue Mr Schaden chose for the living room was dire - actually "Smurf Blue" would just about describe it. It's a really oppressive colour - I can't think of any other way to describe it. We don't live in a large house, and it just felt though the walls were closing in. And I swear it hurt my eyes.
DS and DIL have a teal blue on one wall - that looks very beautiful, but it's only on one wall (others are pale grey) and looks very striking. On all four walls (like ours was) it would be dreadful in a small room. What was worse was there was a lot of blue left over and Mr S used it up to paint both the porch and the kitchen. Theporch has been repainted, thank Christ - the kitchen is next. However he's just spent five days (FIVE DAYS) fannying on, tidying his big shed and doesn't feel up to a painting job just yet. I may do it myself. Probably just white.
