I'm at work and just took pictures of our pewter swatch. Although its hard to tell in a picture, you can at least be sure it isn't blue-ish 
One is the pewter, one is European grey.
I just looked and realized that they have a completely separate fabric called Euro Satin. And that fabric has its own colors.. All beginning with "European" so there's European blue, pink, etc. The European Satin Grey is the exact same color as the Pewter, just in a different fabric so they call it something different
Hope this helps!
(Sorry they're sideways, can't figure out how to rotate on the work computer!)
