Sonorous Fuchsine
Sonorous Fuchsine (#C21A92) is a true magenta with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (317°, 76%, 43%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin sonōrus, resounding — derived from sonus (sound). As a color modifier, sonorous implies a saturated-and-richly-vibrating quality where the hue carries the deep-resonance visual register of a cathedral-organ-pipe low-note. Sits at the bold-and-resonant end of the grid, parallel to resonant and deep in usage.
Synthetic-organic dye class first synthesized in 1859 by François-Emmanuel Verguin from aniline-and-tin-chloride. The dye was named after the fuchsia flower for its deep-magenta hue. Fuchsine color refers to a freshly fuchsine-dyed Lyon silk faille: a saturated, slightly cool deep magenta with the silky luster of synthetic aniline dye. Contemporary with mauveine, solferino, and the Battle of Magenta.

How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
