I am a teenage boy with a large bedroom. At the moment it is painted two shades of blue. I have black-brown furniture and a wooden floor. I have quite a lot of natural light. I would like to change the colours of my walls but am struggling for inspiration. I like grey tones, but on their own I think that they look boring and dull. I think I would like three of the 4 walls to be a simple, light tone and the 4th to be a bold colour. Any Ideas??
