Before: please excuse the mess.
The original walls were a light beige/off white color. After digging around in the garage, I discovered that the previous owners had left a gallon of paint that would work well in the master bathroom. The color wasn't labeled, but it looks like a dark beige or maybe Straw Basket (http://www.behr.com). I painted four walls this color. I contrasted this color by painted two walls Chocolate Swirl; also by Behr. I choose to paint the "hidden" walls the dark chocolate color. The idea was that the dark color was hidden from the outside view, and would be a surprise once you were inside of the bathroom. In addition, I thought that the dark paint above the sink would really bring out the white trim around the mirror and white counter top. I love the initial decor above the toilet. At first my husband thought it was weird to highlight the toilet...lol...but I think it grew on him. The lettering I bought at Michael's craft store and used left over chocolate swirl paint to match the color with the walls. The curtains I bought on sale @ JCPenny. I took one curtain panel, cut it in half and sewed a new seam on the outside panel. I'm very happy with the results.
