The color Pewter is a Silver Gray color.
The color pewter is made using a range of alloys of tin with various amounts of antimony, copper, and in some cases lead.
If the color pewter has more copper then it might have a bit of a copper hue to it, but more commonly it is a metallic combination of a silver and gray color.
So in a way the color pewter is more of a gray color but some people think that the color pewter looks more of a silver color.
To me it looks like a combination of gray and silver which it really is especially if you look at it a certain way and the sun is shining on it.
The color pewter is a very nice color when it comes to a silver and gray color paint.
