Ebon Sienna
Ebon Sienna (#602B18) is a deep orange 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 (16°, 60%, 24%) 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
A poetic shortening of ebony — used principally in nineteenth-century verse and Edgar Allan Poe (The Raven — ebon bird). As a color modifier, ebon is a literary register for deep black with slight warmth, distinct from the cooler inky and the harder jet. Carries the same weight as the wood it borrows from.
Named for the Tuscan city of Siena, which lent its name to the iron-rich earth pigment ground from local clay since the Renaissance. Raw sienna is a warm yellow-brown; burnt sienna is the same earth fired in a kiln to a deeper red-orange. The color refers to the burnt form: a warm, dusty orange with the matte finish of mineral pigment, used in Florentine fresco and oil painting alike.

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.
