Sterile Tufted 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.

Old French touffe, tuft. As a color modifier, tufted implies a hand-tufted-and-puffed quality, the visual register of Edwardian-and-Belle-Époque-tufted-upholstery hand-tufted-and-puffed-and-upholstered velvet-and-silk-and-leather tufted-and-puffed-upholstery surfaces under Edwardian-and-Belle-Époque hand-tufted-upholstery-and-cushion light. Sits at the modifier-and-texture end of the grid, parallel to fluff and flock 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.
