Stone sits a neutral / achromatic tone, with the hex code #888C8D mapping to rgb(136, 140, 141) in RGB and hsl(192, 2.1%, 54.3%) in HSL. In OKLCH it carries 64% perceptual lightness and 0.005 chroma — a desaturated, dark reading that behaves well as a primary, accent or decisive colour in modern interfaces. Neutrals are the connective tissue of every design system — backgrounds, borders, body copy and surfaces all live here. Their psychology is contextual: warm neutrals feel inviting and editorial, cool neutrals feel technical and precise.

Neutrals are where contrast bugs hide — a body text grey of #777 on white fails AA. Audit every neutral against its actual background, not against pure white or pure black.
