Our master bedroom is big and has 2 windows, one of which is a bay, and it is south facing, so tons of natural light. We were planning to paint it a dark blue/navy (f&b stiffkey blue) as we thought this would make it seem more cosy, but a few people have said that's a terrible idea and we should work with the room's natural brightness, not against it.
Carpet is a light grey, bed is upholstered in light natural linen colour, curtains will also be a light colour, ceiling and skirting white.
Let me know what you think!
