Crepuscular Tabebuia

#3c3d26
Notes

Crepuscular Tabebuia (#3C3D26) 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 (63°, 23%, 19%) places it in the muted 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

Crepuscular
adjective

Latin crepusculāris, of twilight — derived from crepusculum (twilight). As a color modifier, crepuscular implies the deep blue-violet darkness of civil-twilight period between sunset and nightfall. Sits at the deep-and-cool end of the grid, where the hue carries the Belt of Venus atmospheric-scattering quality of clear-sky horizon at dusk.

Tabebuia
noun

The genus Tabebuia (now reclassified as Handroanthus) — South American flowering trees whose pendulous racemes of yellow trumpet-flowers cover the canopy in early spring. The color refers to a T. chrysantha (national tree of Venezuela) in bloom: a saturated, slightly red yellow with the satin finish of large trumpet-shaped flowers.
