Many people jump in their seats when you say colorful walls. Let's face it, when it comes to colorful decorating, we have a phobia! I am here to try to take that mentality and toss it in the kitchen garbage can.
Sure, decorating with bold colors has the potential to turn out a disaster, but when done right (and better done by a professional) it can be very elegant, classy, and sometimes soothing. Matter of fact, you can use color therapy to influence your mood in different rooms, such as using soothing cool colors (greens, blues, violets) for a calming environment in the bedroom. Or use bright colors such as red, pink, yellow, to make a statement.
Here are some ideas, notice that these rooms look classy and not scary. Chic and not spooky. Sophisticated and not treacherous... You get the idea.
