Open Tyrol

#426205
Notes

Open Tyrol (#426205) is a deep 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 (81°, 90%, 20%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Open
adjective

Old English open, unobstructed — used as a color modifier since the eighteenth century for hues that read as airy or uncrowded. Open blue, open green: moderate saturation combined with optical spaciousness, the slight visual breath of a hue that doesn't crowd the surface it covers. Sits at the crisp-bucket center alongside clear.

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.
