Heartening Linden

#efc36e
Notes

Heartening Linden (#EFC36E) is a true amber with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (40°, 80%, 68%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Heartening
adjective

Old English heorte (heart) — present-participle of hearten. As a color modifier, heartening implies a clear-and-uplifting-and-encouraging quality where the hue carries the visual register of cheerful-encouraging color-tone. Sits at the crisp-and-cheerful end of the grid, parallel to welcoming and cheerful in usage.

Linden
noun

The genus Tilia — the European linden or basswood, whose pale yellow-green flowers perfume European parks in early summer and yield the tilleul tisane of French herbal medicine. The color refers to fresh linden flowers in June: a soft, slightly green-shifted pale yellow with the matte finish of small clustered florets.

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.
