Bracing Acquerello

#13bb69
Notes

Bracing Acquerello (#13BB69) is a true teal with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (151°, 82%, 40%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bracing
adjective

Old French bracier, to embrace — present-participle of brace. As a color modifier, bracing implies a saturated-and-cool-and-energizing quality, the bright color of Atlantic-Cornish-coast and Hebridean-island fresh-sea-air visual-stimulation. Sits at the bright-and-cool end of the grid, parallel to invigorating and crisp in usage.

Acquerello
noun

The Italian word for watercolor — used for the soft, washed-out blue-greens characteristic of Italian Renaissance watercolor underpainting. Acquerello color refers to a watercolor wash on damp paper: a soft, slightly cool pale blue-green with the translucent finish of pigment-and-water on rag paper.
