Sterling

Sterling looks like brushed metal that's been left in shade a little longer. It's a light gray, but it doesn't feel airy the way some near-whites do. Compared to Murmur, it's slightly more "sprung," less plaster-soft, so it keeps a firmer edge in layouts. Versus Infusion, Sterling reads a touch drier and more matte, with less of that office-glass sheen.

I use Sterling when the UI needs a calm, clean field that still holds panel boundaries. It works well for dashboards and finance apps that want clarity without drifting toward green or warmth, and it's handy in healthcare admin screens where cards, tables, and section headers need to stay legible as you scan. Compared to Flip a Coin, Sterling is lighter and less decisive, so it won't overpower typography, but it also won't disappear next to white the way paler grays can.

Pair it with one step deeper strokes for borders and type. If you stack too many Sterling-adjacent tones, the whole section starts to feel samey instead of structured.
