Lucid Ginkgo

#a19f33
Notes

Lucid Ginkgo (#A19F33) is a true 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 (59°, 52%, 42%) 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 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.

Ginkgo
noun

Ginkgo biloba, the Chinese tree species predating dinosaurs — a living fossil whose fan-shaped leaves turn brilliant yellow in autumn. Often called the maidenhair tree. The color refers to a Ginkgo canopy at peak autumn color: a saturated, slightly cool deep yellow with the satin finish of carotenoid-rich autumn leaves.
