Sparkling Yomogi

#8fb007
Notes

Sparkling Yomogi (#8FB007) is a true yellow 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 (72°, 92%, 36%) 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

Sparkling
adjective

Old English spearca, spark — present-participle of sparkle. As a color modifier, sparkling implies a saturated-and-multi-point-reflective-and-effervescent quality, the bright color of Champagne-and-Prosecco effervescent-wine carbonation-bubble-light reflection. Sits at the bright-and-reflective end of the grid, parallel to glittering and fizzy in usage.

Yomogi
noun

Artemisia indica, Japanese mugwort — used in yomogi-mochi (mugwort rice cakes) and as a traditional moxibustion herb. Yomogi-iro refers to the slightly muted yellow-green of fresh mugwort leaves: a soft, slightly muted yellow-green with the matte finish of pubescent leaf surface. Drier than wakaba.
