Resounding Brazilwood

#ad331e
Notes

Resounding Brazilwood (#AD331E) 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°, 70%, 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

Resounding
adjective

Latin resonāre, to echo back — present-participle of resound. As a color modifier, resounding implies a saturated-and-echoing-and-imposing quality where the hue reverberates visually like a cathedral-bell ring. Sits at the bold-and-resonant end of the grid, parallel to resonant and booming in usage.

Brazilwood
noun

Caesalpinia echinata, the dye-source tree of Atlantic-coast South America — so abundant in Portuguese-controlled territory that it gave the country its name. The color refers to brazilein-dyed silk: a saturated, slightly cool deep red with the warm-tone of brazilwood pigment. Deeper than madder, warmer than cochineal.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
