Etymology

Trustworthy
adjective

Old English trēow, trust — adjectival suffix -worthy. As a color modifier, trustworthy implies a clear-and-reliable-and-honest quality where the hue carries the visual register of confidence-deserving-and-faithful-performance design-element. Sits at the crisp-and-honest end of the grid, parallel to reliable and dependable in usage.

Twill
modifier

Old English twili, twill-weave. As a color modifier, twill implies a diagonal-weave-textile quality, the visual register of Harris-Tweed-and-Italian-gabardine-twill hand-woven-and-diagonal-twill wool-and-cotton-and-silk Harris-Tweed-and-Italian-gabardine-twill-textile surfaces under Harris-Tweed-and-Italian-gabardine hand-woven-twill workshop-light. Sits at the modifier-and-texture end of the grid, parallel to woven and quilt 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.
