Straightforward Hera Moss

#81a45f
Notes

Straightforward Hera Moss (#81A45F) is a true lime with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (90°, 27%, 51%) places it in the muted band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Straightforward
adjective

English compound straight + forward — sharing root with German geradeaus. As a color modifier, straightforward implies a clear-and-direct-and-unencumbered quality where the hue carries the visual register of clear-aim-and-uncomplicated character. Sits at the crisp-and-honest end of the grid, parallel to candid and direct in usage.

Hera
modifier

Greek Ἥρα, queen-of-the-Olympian-gods. As a color modifier, hera implies a peacock-feather-and-queen-of-gods quality, the visual register of Olympian-Hera-and-Argos-temple hand-peacock-feather-and-queen-of-gods Olympian-Hera-and-Argos-temple-and-Heraion-of-Samos hera-and-peacock-feather-and-queen-of-gods surfaces under Olympian-Hera-and-Argos-temple-and-Heraion-of-Samos Polyclitus-and-Argive-and-Samian peacock-throne-light. Sits at the modifier-and-myth end of the grid, parallel to zeus and diana in usage.

Moss
noun

Bryophyta — the nonvascular plants that colonized land 470 million years ago, before vascular plants and far before flowers. The color refers to a thick mat of Hypnum or sphagnum on a temperate forest floor: a soft, slightly yellow-shifted green with the velvet texture of millimeter-scale leaves. Dustier than fern, deeper than lichen, with the slow patience of a plant that lives by absorbing rain through its surface.
