Mapped Atrium Moss

#165c3b
Notes

Mapped Atrium Moss (#165C3B) is a deep teal 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 (152°, 61%, 22%) 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

Mapped
adjective

Latin mappa, cloth / napkin — past-participle of map. As a color modifier, mapped implies a clear-and-cartographic-and-surveyed quality, the crisp color of Ordnance-Survey-and-USGS scientific-and-cadastral cartographic-and-topographic mapping-and-projection. Sits at the crisp-and-mapped end of the grid, parallel to plotted and surveyed in usage.

Atrium
modifier

Latin atrium, Roman-house-courtyard. As a color modifier, atrium implies a Roman-and-modern-courtyard-with-skylight quality, the visual register of Roman-Pompeii-and-modern-Mid-Century-Modern-atrium hand-built central-courtyard-with-skylight atrium-and-impluvium-and-courtyard architectural surfaces under Roman-and-Mid-Century-Modern atrium-skylight light. Sits at the modifier-and-architecture end of the grid, parallel to loggia and quad 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.
