Wellbred Gyokuro

#179837
Notes

Wellbred Gyokuro (#179837) is a deep green 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 (135°, 74%, 34%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Wellbred
adjective

Old English wel-brēd, well-bred — past-participle of breed, sharing root with brood (offspring). As a color modifier, wellbred implies a saturated-and-elegant-and-formal quality, the deep-rich color of Edwardian-period finishing-school-and-debutante-Court English-aristocratic livery. Sits at the bold-and-elegant end of the grid, parallel to highborn and patrician.

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.
