Trustworthy Rush
Trustworthy Rush (#285F07) 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 (98°, 86%, 20%) 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
Old English trēow, trust — adjectival suffix -worthy. As a color modifier, trustworthy implies a clear-and-reliable-and-honest quality where the hue carries the visual register of confidence-deserving-and-faithful-performance design-element. Sits at the crisp-and-honest end of the grid, parallel to reliable and dependable in usage.
The genus Juncus — wetland sedge-family plants whose hollow green stems were used historically for rushlights (torches dipped in tallow) and traditional weaving. The color refers to a clump of fresh rushes in a damp meadow: a saturated, slightly cool deep yellow-green with the matte finish of round hollow stalks.
