Sterile Virgo Moss

Latin sterilis, barren / not-fertile — sharing root with Greek steiros (barren). As a color modifier, sterile implies a clear-and-medical-clean-and-stripped quality, the crisp color of operating-theater surgical-environment white-and-stainless-steel surfaces. Sits at the crisp-and-clean end of the grid, parallel to sanitary and hygienic in usage.

Latin virgo, virgin-or-maiden-of-the-zodiac. As a color modifier, virgo implies a maiden-and-earth-sign-and-Mercury-ruled-mutable-earth quality, the visual register of Hellenic-Virgo-and-Astraea-maiden hand-maiden-and-earth-sign-and-Mercury-ruled-mutable-earth Hellenic-Virgo-and-Astraea-maiden-and-Spica-grain virgo-and-maiden-and-earth-sign surfaces under Hellenic-Virgo-and-Astraea-maiden-and-Spica-grain late-summer-and-August-and-September mutable-earth-sign-light. Sits at the modifier-and-zodiac end of the grid, parallel to leo and libra in usage.

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.
