Glowing Tabebuia

#b59c15
Notes

Glowing Tabebuia (#B59C15) is a true amber with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (51°, 79%, 40%) 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

Glowing
adjective

The progressive participle of glow, to emit light — used as a color word since the medieval period for hues that read as if they were luminous from within. Glowing amber, glowing rose: the implication is moderate saturation combined with the optical impression of internal light. Sits in the bright-bucket alongside radiant.

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.
