Tough Glee Brick

#a5391c
Notes

Tough Glee Brick (#A5391C) is a true red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (13°, 71%, 38%) 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.

Glee
modifier

Old English glēo, music-or-merriment. As a color modifier, glee implies a singing-and-merry-and-bubbling quality, the visual register of Elizabethan-glee-club-and-madrigal-glee hand-singing-and-merry-and-bubbling Elizabethan-glee-club-and-madrigal-and-catch-singing gleeful-and-singing-and-merry-and-bubbling surfaces under Elizabethan-glee-club-and-madrigal-and-catch-singing parlor-and-tavern-and-court candlelit-music-light. Sits at the modifier-and-mood end of the grid, parallel to mirth and merry 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.
