For painting dark and ultra-deep colors in a room or exterior, some will use 3-4 coats of paint to make sure the surface represents the true color desired. That can be quite expensive! If you ask a professional painter interested in saving you money and time, you can do this simple painting trick: First apply a primer tinted dark grey over the area you want to paint. Primer is cheaper than paint and the dark grey tint helps for color adhesion. You should be able to paint as normal, achieving the true color with only 2 coats. This was the tip of the day from your RC Painters, Colorado Springs.
