Pewter and silver looks like silver and sometimes looks like grey in different lighting conditions and at different angles.
Pewter and Silver are in a way the same color but actually Pewter is both silver and grey in color.
The Pewter color is a grey and silver color combination but some people think that Pewter is just grey while other people think that the Pewter color is a silver in color.
But actually the Pewter color is a combination of the silver and grey colors but it can depend on the angle that you look at the color Pewter.
Sometimes to myself in some sunlight and at a certain angle Pewter looks silver in color while other times when the sun is not shining on it as much the Pewter looks more grey.
