DS is nearly 5 and it's time to redecorate his room (same colours since he was born). Anyway, he is adamant that he wants it bright blue. It's quite a small room so a bit worried this will be a bit overwhelming. I have bought a Marvel Superhero Comic mural that will break up the biggest wall. Am I best to just have one wall bright blue and the rest a more subtle light blue, am thinking Dulux Mineral Mist? Or are 'feature walls' a no-no these days (have read this on MN a few times but can't see how you avoid them with certain colours and wallpapers, and surely it's about what looks good and doesn't hurt your eyes?). So has anyone incorporated a really bright blue in a bedroom and how? Thanks.
