Dense Welsh Crimson

Latin dēnsus, thick / crowded — sharing root with English condense. As a color modifier, dense implies a saturated-and-tightly-packed quality where the hue carries maximum pigmentation per visual unit-of-area. Sits at the bold-and-saturated end of the grid, parallel to thick and concentrated in usage.

Old English Wælisc, of-Wales. As a color modifier, welsh implies a Cymric-and-slate quality, the visual register of Welsh-Cymric hand-built slate-and-stone-and-Welsh-wool valley-and-mountain hand-spun-and-hand-quarried surfaces under Welsh-Cymric Snowdonia-and-Brecon-Beacons valley light. Sits at the modifier-and-cultural end of the grid, parallel to celtic and scot 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.
