Pewter is a color between silver and deep gray and has a mild luster. The color derives from pewter, an alloy of tin and other metals, such as copper and bismuth, and metalloids, such as antimony.
Pewter is considered a neutral color and blends well with colors that are more emphatic. Pewter is also used as an exterior color for the siding, doors and window frames of buildings. It's also used as interior paint, either as an accent color or the main color of a room or area. The soft gray color can also be used in apparel such as formal gowns or men's suits and ties.
