The latest buzz in the Scandinavian design blog crowd is dark walls. It started already at the beginning of the year, but the real breakthrough must have been some weeks ago when the queen of white walls, Lotta Agaton, painted her entire shop/studio in dark hues. I love this look, but it's not for my home which is already way too dark even with white walls. I think you need a lot of daylight to keep dark painted rooms from feeling like you are living in a cave.
These pictures from Tommaso Sartori Studio show lots of great examples of spaces where this look absolutely works!
