The color wall is a screen that wraps one wall, all walls or your whole house. After the screen is installed, all you would need to do to change the color or add a design is place the chip in the control box. You can purchase different design or color chips from your local hardware store. You can change one wall or your whole house as many times as you like, whenever want. No mess, no chemicals, no smell. Change them for a birthday party or graduation. In the future painting is a breeze!
