Straightforward Lyra Moss

#618031
Notes

Straightforward Lyra Moss (#618031) is a true lime 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 (84°, 45%, 35%) places it in the balanced 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.

Lyra
modifier

Greek λύρα, lyre-of-Orpheus. As a color modifier, lyra implies a small-summer-constellation-and-Orpheus-lyre quality, the visual register of summer-Lyra-and-Orpheus-lyre hand-small-summer-constellation-and-Orpheus-lyre summer-Lyra-and-Orpheus-lyre-and-Bortle-1-sky lyra-and-small-summer-constellation-and-Orpheus-lyre surfaces under summer-Lyra-and-Orpheus-lyre-and-Bortle-1-sky July-and-August-summer-zenith ring-nebula-and-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to vega and cygnus 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.
