About charcoal

A dark blue-grey named after burnt wood. It is the popular "not quite black" dark-mode surface — enough blue to feel cool without going navy.

The values above are computed from the sRGB hex #36454F. The OKLCH form (oklch(38.1% 0.0258 237.54)) 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 9.9:1 and against black 2.12:1 — use whichever clears the bar for the text you place on it.
