One of the changes I made this month for Dress Your Walls was to paint the bedroom blue. It used to be a drab beige with a weird brown border along the bottom (this was pre-CasaSugar move-in), and it took two coats of low-VOC primer and two more coats of low-VOC paint to get the color right.
Cool colors, such as blue, brown, and grey, are thought to promote concentration and calmness. so they're great for bedrooms and offices. I know that I feel calm and happy whenever I walk into our new blue bedroom.
my mom's place is all blue (not that shade, though) and it is so relaxing to be there.
My brothers bedroom (and my old old one) was blue with clouds on it and it was so relaxing! I love it!
