New York, NY
We just moved into a lovely, but MUCH SMALLER apartment. Molly's old room, which she'd had since she was 2, was more than twice the size of the new one. So, to make it seem worth her while, we let Molly choose her own colors. One wall was to be painted orange, yes, tangerine orange (okay, the "one wall" part was influenced by her loving parents!), and the others a very pale pink. The whole room is outfitted in hot pink and orange, with a breath of black and white to tame it all down. While Molly was the boss, she had lots of "help" from her parents; and from a brilliant architect/designer, Roberto Gil and resourceful decorator.
Tip for Using Color:
Despite the bold accents, we chose a neutral palette for the furniture and used patterns and bold colors in the fabrics and one wall. I wanted Molly to have a fun and fabulous (and functional) room in which to grow, so the furniture couldn't look too child-like. The colors of the wall and the fabrics can be replaced for a whole new look later on, if Molly feels she wants a change. There are accent colors throughout that are as warm and the same intensity as the orange wall so it all ties together.
Colors Used: Orange, hot pink, black and soft white. All Benjamin Moore colors.
Thanks for your colorful entry Margo and good luck!
