Lucid Bancha

#1b5d2a
Notes

Lucid Bancha (#1B5D2A) is a deep green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (134°, 55%, 24%) 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

Lucid
adjective

Latin lūcidus, clear / bright — derived from lūx (light). As a color modifier, lucid implies a clear-and-readable quality where the hue is unambiguous and free of optical clutter. Sits at the crisp-and-clear end of the grid, parallel to pellucid and plain in usage.

Bancha
noun

The Japanese green tea made from later-season Camellia sinensis leaves — milder than sencha, lower in caffeine, and traditionally drunk with meals across rural Japan. The color refers to fresh-brewed bancha: a soft, slightly cool deep blue-green with the optical clarity of late-season green-tea liquor.

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.
