Thin, reflective frames in gold, silver or gunmetal tones.

Thin metal frames generally carry the least visual weight of any frame style, which is why the frame's own metal tone (cool pewter-grey here) tends to matter more for coordination than the frame shape itself.

Generally the lowest-visual-weight frame option, since the thin metal recedes more than a bold plastic frame.
A subtle, versatile option that rarely dominates an outfit.
Rarely a dominant factor, given the frame's lighter visual presence.

A thin wire frame occupies so little area that its colour barely registers; what the eye picks up instead is a line of highlights. A polished metal rim mirrors the room, so it flashes bright wherever it faces a lamp or window and shows its own tint — gold's missing blue, silver's neutrality, gunmetal's dark grey coating — only in the spaces between. That is why metal frames read as light and delicate even in dark finishes, and why the metal's warmth matters more than its exact colour.
The material: Frame metals are often plated or coated, so the visible colour is a surface layer over the base alloy; matte or brushed finishes turn the bright line of highlights into a softer, steadier tone.
