Cimmerian Cobalto
Cimmerian Cobalto (#061C4A) is a deep azure 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 (221°, 85%, 16%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
From the Cimmerians of Homer's Odyssey — a legendary people who dwelled at the western edge of the world in perpetual darkness. As a color modifier, cimmerian implies a literary-poetic register for absolute darkness without sunlight. Sits at the deepest end of the grid, parallel to Stygian with classical literary connotations.
The Italian word for cobalt — used for the saturated deep blue of cobalto-glaze on Tuscan and Venetian Renaissance ceramics. The color refers to a cobalto-glazed Tuscan piatto: a saturated, slightly cool deep blue with the high gloss of cobalt-glazed porcelain. The Italian cousin of cobalt.

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.
Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
