You may love white walls and matching slipcovered furniture, but your tween probably isn't as into the minimalist approach. Tweens are still developing their styles at this age, and more than likely, they still want some color in their lives. You may abhor the idea of bright pink or deep purple walls, but that's how your tween's choosing to express an individual sense of style. At least for a little while. So pick your battles -- paint is an impermanent way to let your tween take the lead.
