Ombre wall paint inspiration, on trend for 2016. Love the transition of dark to light blue here, especially how well it contrasts with white furniture. Blue and white work very well together and here's a way of introducing blue without giving screaming "beach house".
Paint the existing wooden wall cladding, behind the bed in a charcoal colour and replace existing bedside tables with modern white ones. This will break up the amount of yellow beach wood in the room and also give the bed an identity of its own.
