Master bedroom colors - This is very close to the mid-century chocolate and turquoise palette that I love so much. The blues need to be more turquoise (or aqua) than these sea-foam colors, and the gray could also be a very pale pink for a lighter touch.
I really like the look and the dark wall! Love the black wall - make it an accent wall? Hardwood floors with rugs for master bedroom. This is what my bedroom will look like when we move! But with blue walls and a black wall.
