Cimmerian Daylily
Cimmerian Daylily (#40170A) 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 (14°, 73%, 15%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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
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 genus Hemerocallis — day-beauty in Greek — perennial lily-relatives whose individual flowers bloom for a single day before wilting. The color refers to a fresh orange daylily H. fulva on a roadside: a saturated, slightly red orange with the satin finish of trumpet-shaped flower. Brighter than tangerine, with the ephemeral weight of a flower whose bloom lasts hours.

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.
