I'm about to order some prescription Square Wires with VR28 BIP lenses and wanted to get some advice on the frame color. Can someone tell me what color the tungsten frames are? In some images they look like a polished gunmetal color, but on the Oakley site they have more of a brown tint (see below). Would these look good with the VR28 BIP or should I go with black or chrome? Thanks!
