Lustrous Dahlia

#fb7e2a
Notes

Lustrous Dahlia (#FB7E2A) is a true orange with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (24°, 96%, 57%) 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

Lustrous
adjective

From the Latin lustrare, to illuminate — used as a color word since the seventeenth century for hues with the slight specular shine of polished metal or silk. Lustrous green, lustrous gold: the implication is moderate-to-high saturation combined with surface reflectivity. Sits at the bright-and-glossy corner alongside gleaming.

Dahlia
noun

The genus Dahlia — Mexican composite-family flowers bred across the nineteenth century into thousands of cultivars in every color from white to dark purple. The color refers to a fully opened orange decorative dahlia: a saturated, slightly red orange with the satin finish of multi-rayed composite flower. Warmer than zinnia, deeper than calendula.

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.
