Unblemished Tawny

#66410f
Notes

Unblemished Tawny (#66410F) 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 (34°, 74%, 23%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Unblemished
adjective

Old French blesmir, to wound — negative-prefix un- plus past-participle of blemish. As a color modifier, unblemished implies a clear-and-flawless quality where the hue carries no defect or imperfection. Sits at the crisp-and-clean end of the grid, parallel to pristine and spotless in usage.

Tawny
noun

From the Old French tané, tanned — originally the brown of leather tanned with oak bark. The color now describes the gold-brown of a lion's coat, the autumn flank of a fox, the ground color of a tawny owl. Warmer than wheat, more saturated than tan, with the animal-fur warmth of a word that almost always describes living things rather than objects.

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.
