Sonorous Hour violet
Sonorous Hour violet (#9F226F) is a true magenta 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 (323°, 65%, 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 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.
Latin hōra, time-of-day. As a color modifier, hour implies a single-time-period quality, the visual register of Edwardian-and-Victorian household clock-marked single-hour-of-the-day domestic-and-formal interior surfaces under hour-by-hour pendulum-clock day-light. Sits at the modifier-and-time end of the grid, parallel to bell and vesper in usage.
Viola odorata, the European sweet violet — small, fragrant, and the original meaning of the color name in English (the Violet of the rainbow). The color refers to a fresh sweet violet blossom in late winter: a saturated, slightly red-shifted deep blue-purple with the matte finish of small five-petaled flower. Cooler than amethyst, warmer than indigo, with the perfumed weight of a flower used in Roman garlands and Victorian eau de toilette.

Accessibility
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.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
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.
