Fiery Tyrol

#63aa17
Notes

Fiery Tyrol (#63AA17) is a true lime 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 (89°, 76%, 38%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Fiery
adjective

Old English fȳr, fire — adjectival suffix -y. As a color modifier, fiery implies a saturated-and-bright-flaming quality, the bright color of autumn-foliage fall-color and forge-furnace hot-iron emission. Sits at the bright-and-warm end of the grid, parallel to flaming and blazing in usage.

Tyrol
noun

The Alpine region split between Austria and northern Italy — and the deep green of Tyrolean Alpine pasture and the grün lederhosen of traditional Austrian dress. Tyrol color refers to a Tyrolean Alpine meadow in July: a saturated, slightly cool deep yellow-green with the matte finish of high-altitude wildflower-and-grass.
