Indomitable Bottle

#256813
Notes

Indomitable Bottle (#256813) is a deep green 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 (107°, 69%, 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Indomitable
adjective

Latin indomitābilis, unconquerable — derived from domāre (to tame). As a color modifier, indomitable implies a saturated-and-unconquerable-and-fierce quality where the hue resists any attempt to subdue or modulate its presence. Sits at the bold-and-resilient end of the grid, parallel to unyielding and adamant.

Bottle
noun

The traditional dark green of European wine and beer bottles — produced by adding iron oxide to the glass batch to filter UV that would damage the contents. The color refers to a Riesling or Burgundy bottle held against the light: a deep, slightly blue-shifted green with the optical translucency of glass. Darker than spruce, cooler than forest, with the cellar weight of a color that's been protecting wine since the seventeenth century.

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.
