Ostentatious Tabebuia

#a2b306
Notes

Ostentatious Tabebuia (#A2B306) is a true 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 (66°, 94%, 36%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Ostentatious
adjective

Latin ostentātiōnis, display — adjectival suffix -ous, derived from ostendere (to show). As a color modifier, ostentatious implies a saturated-and-attention-demanding-and-elaborate quality, the bright color of Belle-Époque-and-Gilded-Age showy-luxury-display interior-decoration. Sits at the bright-and-flamboyant end of the grid, parallel to flamboyant and showy 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.
