About silver
A light neutral grey standing in for the metal. As an equal mix of red, green and blue it is perfectly desaturated — a useful UI border or disabled state.
The values above are computed from the sRGB hex #C0C0C0. The OKLCH
form (oklch(80.8% 0 0)) is worth noting: unlike HSL, its lightness matches
how bright the colour actually looks, which makes building consistent shade scales far
easier. To tweak this colour or convert one of your own, open the full
colour converter, and check readable text pairings
with the contrast figures shown above.
Accessibility note: text needs a contrast ratio of at least 4.5:1 for normal body copy under WCAG AA. Against white this colour scores 1.82:1 and against black 11.54:1 — use whichever clears the bar for the text you place on it.
