Adamant Dill Ruby

#b54642
Notes

Adamant Dill Ruby (#B54642) is a true red with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (2°, 47%, 48%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Adamant
adjective

Greek adámas, unconquerable — derived from a- (not) plus damnan (to subdue). As a color modifier, adamant implies a saturated-and-rock-hard quality where the hue maintains diamond-hard pigmentation. Sits at the bold-and-resilient end of the grid, parallel to indomitable and ironclad in usage.

Dill
modifier

Old English dile, aromatic-fern-leaf-herb. As a color modifier, dill implies a feathery-and-fresh-and-pickling quality, the visual register of Scandinavian-and-pickling-dill hand-feathery-and-fresh-and-pickling Scandinavian-and-pickling-dill-and-Polish-Eastern-European dill-and-feathery-and-fresh-and-pickling surfaces under Scandinavian-and-pickling-dill-and-Polish-Eastern-European Stockholm-and-Gdansk-and-Riga-pickling-jar Baltic-pickling-light. Sits at the modifier-and-flavor end of the grid, parallel to chive and anise in usage.

Ruby
noun

From the Latin ruber — simply, red. The gemstone is a chromium-tinged corundum, harder than anything in nature except diamond, and so saturated that a fine Burmese pigeon's blood ruby at auction outpaces a comparable diamond by weight. The color borrows the gem's confidence: a clear, glassy red without the brown of garnet or the blue of crimson.

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.
