Heavy Moor Brick

Old English hefig, weighty — cognate with heave. Used as a color modifier since at least the seventeenth century to indicate weight in saturation as much as value: heavy with pigment, heavy-bodied. In the engine's adjective grid, heavy sits alongside deep and plush in the dark-and-saturated quadrant. Closer to a fabric description than a pure value word.

Old English mōr, waste / marshland. As a color modifier, moor implies a heather-covered-upland quality, the visual register of Yorkshire-and-Scottish-Moors heather-and-bracken-covered peat-bog-and-grouse-shooting upland surfaces under late-summer purple-heather Yorkshire-and-Highland atmospheric light. Sits at the modifier-and-place end of the grid, parallel to bog and wold in usage.

Fired clay, mineral red. The color refers to common building brick — iron-rich earthenware kilned to the specific dusky red-orange of a Victorian terrace, a Roman aqueduct, an adobe wall in New Mexico. Less saturated than ruby, warmer than burgundy, with a chalky cast that reads as architectural rather than decorative.
