Stimulating Gyokuro

#01c0a1
Notes

Stimulating Gyokuro (#01C0A1) is a true teal 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 (170°, 99%, 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Stimulating
adjective

Latin stimulāns, spurring on — present-participle of stimulate, derived from stimulus (a goad). As a color modifier, stimulating implies a saturated-and-arousing-and-attentive quality where the hue increases visual-and-cognitive engagement. Sits at the bright-and-active end of the grid, parallel to invigorating and bracing in usage.

Gyokuro
noun

The premium Japanese green tea grown in shade for three weeks before harvest — concentrating chlorophyll and theanine. Gyokuro (玉露 — jewel dew) is the most expensive non-matcha Japanese tea. The color refers to fresh-brewed gyokuro: a saturated, slightly cool deep blue-green with the optical depth of shaded-leaf tea.

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.
