So maybe painting an open space of approximately 375 square feet in a dark dark blue might be just a little too much? Instead, these grey-greens are calling to me, definitely lighter that the rooms pictured here but still able to provide a calm, enveloping feeling.
All colours from Benjamin Moore:
1. Croquet 2. Aganthus Green 3. Paris Rain 4. Tree Moss
I am personally leaning towards the Aganthus Green because of its' slightly cooler tone AND the fact that I totally love this room below. Ok so we don't have 10' ceilings, paneled molding or floor-length, fringed cream-coloured curtains, but it DOES look so good with the dark wood, sisal, persian rug and grey upholstery which are all elements one could feasibly incorporate into one's room.
