Functional Linden

#ad6915
Notes

Functional Linden (#AD6915) is a true 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 (33°, 78%, 38%) 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

Functional
adjective

Latin fūnctiō, performance — adjectival suffix -al. As a color modifier, functional implies a clear-and-purpose-fit-and-utilitarian quality, the crisp color of Mid-Century-Modern and Bauhaus form-follows-function design-aesthetic. Sits at the crisp-and-functional end of the grid, parallel to practical and utilitarian 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.
