Room decorating ideas for a 15 year old girl…..?

A medium to dark shade of gray would look nice with the light purple, and if you add some dark purple to your room it would add nice depth and drama. It's also a nice neutral color, and would go well with so many other color schemes you might come up with in the future. Gray is a nice change for a neutral from the usual tans and beiges. Add some yellow in your room for some pop and cheeriness. Since your room is small, keep your window coverings light and airy, just have a blind that you can close for when you need privacy. Try adding a large mirror on the wall directly across from the window to add additional 'natural' lighting, it will also make the room appear bigger. Look for some large pictures to hang with some depth to them, like a field going on forever, a road heading away, a picture with a lot of sky, etc., to give the feeling of roominess. Keep the room in a minimalist fashion, too much clutter will make it feel even smaller. Try hanging a grouping of smaller mirrors together to reflect light and preferably something pretty. For a different headboard, look for old albums in your favorite bands and hang the album covers directly above your bed, edge to edge, the width of your bed, as high as you want for drama and a style that is truly you. Have fun in your new room and good luck.
