Croft Crypt
Croft Crypt (#2B0102) 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 (359°, 95%, 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
Old English croft, small-enclosed-field — adjectival usage of croft. As a color modifier, croft implies a neutral-and-Scottish-Highland-and-traditional quality, the neutral color of Scottish-Highland-Crofter hand-spun-and-hand-woven crofting-and-pasture traditional-craft textile-finish. Sits at the neutral-and-traditional end of the grid, parallel to homespun and folksy in usage.
Greek kryptē, hidden-chamber — the deep-cool-gray underground-chamber of medieval European cathedral-and-basilica architecture, particularly the San-Marco-Venice and Santa-Cruz-Coimbra royal-crypt chambers. Crypt color refers to a Saint-Denis-Basilica royal-crypt chamber face in candlelight: a dark cool-gray with the matte finish of Île-de-France-Lutetian-limestone hand-quarried 12th-century Capetian-royal-mausoleum architecture.

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.
