Lucid Tarragon

#646f29
Notes

Lucid Tarragon (#646F29) is a deep yellow 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 (69°, 46%, 30%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Lucid
adjective

Latin lūcidus, clear / bright — derived from lūx (light). As a color modifier, lucid implies a clear-and-readable quality where the hue is unambiguous and free of optical clutter. Sits at the crisp-and-clear end of the grid, parallel to pellucid and plain in usage.

Tarragon
noun

Artemisia dracunculus, the French tarragon — small narrow-leaved relative of wormwood whose volatile oil tastes faintly of anise. The color refers to fresh tarragon leaves on the stem: a saturated, slightly muted green with the matte finish of a Composite-family leaf surface. Cooler than basil, lighter than spinach, with the kitchen specificity of a herb that defines béarnaise and a French roast chicken.

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.
