Color washing is a subtle effect perfect for almost any wall in your home, giving your walls an elegant, warm and textured look. This beautiful painting technique is created by blending various shades of related colors. Color washing your walls can give the impression of a aged or plastered finish. It can stand alone as a beautiful background, or act as the base layer for sky scenes and multi-layered marble finishes, and can be done over textured plaster finishes or existing brickwork.
