Hefty Tabebuia

#8a9610
Notes

Hefty Tabebuia (#8A9610) is a deep yellow 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 (65°, 81%, 33%) places it in the highly saturated band at a dark 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Hefty
adjective

Old English hefig, heavy — adjectival suffix -y. As a color modifier, hefty implies a saturated-and-substantial-and-weighty quality where the hue carries the visual heft of a hand-cast pig-iron object. Sits at the bold-and-weighty end of the grid, parallel to substantial and weighty in usage.

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.

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.
