I'm looking to paint my dining room. It has hardly any natural light as it leads onto other rooms. I need paint colours that are going to help with its dark shadowy ways. It also has a lot going on in the room with a wall cupboard and a total of 4 doorways. I was thinking a blue-green colour or something like a pale blue. From the testers I've tried the colours seem to go quite dull on the wall. Has anyone painted a dark room with success? I'm clueless!
