Adamant Wasabi
Adamant Wasabi (#41960D) 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 (97°, 84%, 32%) 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
Greek adámas, unconquerable — derived from a- (not) plus damnan (to subdue). As a color modifier, adamant implies a saturated-and-rock-hard quality where the hue maintains diamond-hard pigmentation. Sits at the bold-and-resilient end of the grid, parallel to indomitable and ironclad in usage.
Eutrema japonicum, the river-grown rhizome from the cold streams of Honshu, ground fresh into the green paste that accompanies sushi in traditional Japanese restaurants. Most wasabi served outside Japan is dyed horseradish — the real plant is rare and expensive. The color refers to fresh-grated wasabi: a soft, slightly muted yellow-green with the matte finish of a wet plant cell wall, brighter than sage, drier than matcha.
