As always, the walls and the objects on them should work to make the bedroom more attractive and reinforce the overall feeling of quality.
Bedroom wall decor sets up an overall mood of the room. Fill in hairline cracks, cover nail holes, and attend to other cosmetic flaws. Once the surface of the bedroom walls is in proper shape, you can upgrade tem in several different ways. First of all - paint. A fresh coat of paint suggests care and newness. The color of the paint should be neutral, but in the bedroom there is some basis for latitude. Blue, for instance, has a calming effect on people and can be especially appropriate in the bedroom.
You might consider choosing pastel shades and using blue as an accent color. You could also try safe colors like antique white or beige and the soft, neutral pastels; or go with monochromatic color scheme.
If you use pale yellows or a dusty rose, for example, consider highlighting molding by painting them white. This will create visual interest but won't break up wall areas. For children's bedroom, brighter colors are appropriate. Yellow, red, green, or blue can create an atmosphere of fun.
