Tough Merry Brick

#aa3823
Notes

Tough Merry Brick (#AA3823) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (9°, 66%, 40%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Tough
adjective

Old English tōh, firm / tenacious — sharing root with German zäh. As a color modifier, tough implies a saturated-and-resilient quality where the hue resists fading-and-modulation through its strong pigmentation. Sits at the bold-and-resilient end of the grid, parallel to rugged and hardy in usage.

Merry
modifier

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.

Brick
noun

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.
