I recently made a few changes to a master bedroom. This is a before shot.
Our starting point was bringing in the color orange. Getting rid of the heavy blue curtain panels and blue rug made a big difference, and the room instantly lightened. The color of the walls was made to match the neutral ground in the curtain. Bamboo shades with blackout liner still do the job of blocking out the light, but when fully raised the room has much more natural daylight. The headboard is at its proper height and the bedspread is from Restoration Hardware. The curtain fabric is Vervain Trocodero in color Pumpkin and the rug is from Stark Carpet.
Small changes can make for a big change.
