Unyielding Merry Crimson

Old English un- (negation) plus gildan (to give-up). As a color modifier, unyielding implies a saturated-and-uncompromising quality where the hue refuses to fade-or-shift under any visual pressure. Sits at the bold-and-resilient end of the grid, parallel to indomitable and adamant in usage.

Old English myrige, pleasant-and-glad. As a color modifier, merry implies a glad-and-bright-and-festive quality, the visual register of Robin-Hood-Merry-Men-and-Maytime-merry hand-glad-and-bright-and-festive Robin-Hood-Merry-Men-and-Maytime-and-village-fair merried-and-glad-and-bright-and-festive surfaces under Robin-Hood-Merry-Men-and-Maytime-and-village-fair Sherwood-Forest-and-Mayday-and-Whitsun greenwood-festival-light. Sits at the modifier-and-mood end of the grid, parallel to jolly and blithe in usage.

From the Old Spanish cremesin, itself from the Arabic qirmiz — the kermes scale insect, dried and ground into a brilliant carmine dye prized in the medieval Mediterranean. For centuries the most expensive red on a draper's shelf, reserved for cardinals, kings, and the cloth that gave English the word crimson. Cooler than scarlet, deeper than rose; the color of pomegranate seeds and a serious occasion.
