It looks very good with Black Iridium. Very professional, very understated.
Very classic color for when you don't want a deep black, but a less harsh and more charcoal colored frame.
Dark wires look a bit odd on fair skin, so all you Gingers keep that in mind if looking at a pewter frame. Not so bad as a sunglass frame, but as an Rx it would just look too odd on fair skin. Otherwise a good frame color, a bit harder to pull off in a formal situation though.
It's a darker, very subdued shade of metal but it's the perfect contrast for the flashier lenses. They work great with Ruby lenses.
These are cool, and really suit the Hatchets. One of my prefered colourways, though perhaps a little too dark coupled with a black lens.
