Blue is the warmest colour. If you don't have room for a four-poster bed then a pelmet like this one by Paolo Moschino can be a creative alternative. The linen curtains are made from "Nyvelle Oyster" by Paolo Moschino for Nicholas Haslam. The clean, straight lines and border of blue stands out against the dark walls.
