Dark blue is not for the faint of heart, this is a bold color and can dramatically transform a room.  It can be energetic or calming.  Dark colors cause the walls to recede and can make a room feel larger.  As you can see from the rooms pictured below, sometime the blue is bold and very very blue and other times it is a supporting character and becomes a nice neutral backdrop.  Whatever you're feeling there is a blue for you.

Here are some examples of the colors in real rooms:

• Emma Reddington Friday designed this room with Benjamin Moore Deep Space walls.
• Farrow & Ball Stiffkey Blue No. 281
• Hudson Blue in room designed by Twenty One Two Designs Inc
• Sherwin Williams Frank Blue in Butler's Pantry designed by Archer & Buchanan
• Jeannette Wilson painted this room Farrow & Ball Hague Blue for House Beautiful
