One of the most common wallcovering types is the solid. This type comes in many different colors and can show off subdued patterns under some of the colors. From bright colors that make a room lively to natural colors that feel like the great outdoors to neutral colors for a relaxing environment, solids are incredibly versatile. Of course, because there are also different tones to each of the colors, you can create an interesting effect for an area or cluster of rooms.
