Anthracite Crimson

A dark system. The ground and its surfaces are one neutral stepped in lightness, so the page never becomes one hue at nine brightnesses, and the accent carries real chroma so it can mean something when it appears.

Roles

Data colours

Left over after the roles were filled, and kept at full chroma. A chart series is not chrome: it keeps its own colour through a theme change, and these are the ones spoken for.
