Stoic Ardoise
Stoic Ardoise (#2C0201) is a deep red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (1°, 96%, 9%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Greek stōikós, of-the-Stoa — adjectival suffix -ic, referring to the Stoic-Philosophy of Zeno-of-Citium. As a color modifier, stoic implies a neutral-and-restrained-and-unaffected quality where the hue carries the visual register of Stoic-philosophical unaffected-and-stripped-down color-decision. Sits at the neutral-and-restrained end of the grid, parallel to stoical and reserved in usage.
French ardoise, slate — particularly the deep-blue-gray ardoise d'Anjou slate quarried from the Maine-et-Loire and Mayenne slate-belt for Loire-Valley château-roofs. Ardoise color refers to a Château de Chambord ardoise d'Anjou roof-tile face in raking sun: a dark blue-gray with the matte finish of metamorphic Carboniferous slate-shale on a hand-quarried 16th-century roofing tile.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
This color sits well within the sRGB cube. P3 and sRGB share the gray axis and most desaturated tones, so a P3 display renders this identically to an sRGB display.
