Triumphant Naiad

#128d41
Notes

Triumphant Naiad (#128D41) is a deep green 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 (143°, 77%, 31%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Triumphant
adjective

Latin triumphāns, celebrating victory — present-participle of triumphāre. As a color modifier, triumphant implies a saturated-and-celebratory-and-victorious quality, the deep-rich color of Roman-Imperial-period triumphal-arch spolia relief and Arch-of-Titus victory imagery. Sits at the bold-and-celebratory end of the grid, parallel to victorious and conquering.

Naiad
noun

The water-nymphs of Greek mythology — daughters of river-gods who personified the springs, brooks, and lakes of the ancient Mediterranean. Naiad color refers to a Greek mountain spring at midday: a soft, slightly cool deep blue-green with the optical clarity of mineral-spring water emerging into a marble basin.

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.
