Love the purple walls (I can't find the source of this image which is mighty annoying) I love the color scheme but rather in a bedroom or living room. Dark purple walls, gray wainscot, white ceiling and marble gray floor. Metal or silver details.
Pink Pearl - For that Gothic Teenager. Pink walls and Black bedding & accents, done in a classy way. Adding a solid Black Wood blind or Designer Roman shade would be the perfect touch for the window (that we can't see)
