Realgar

Realgar (#E1502A) 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 (12°, 75%, 52%) 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. Arsenic sulfide mineral mined since antiquity for its orange-red brilliance. Used by Renaissance painters and Mughal miniaturists until its toxicity made it obsolete.
