Solid Sewn Violet

#a21b5c
Notes

Solid Sewn Violet (#A21B5C) 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 (331°, 71%, 37%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Solid
adjective

Latin solidus, firm, dense — used as a color modifier since the seventeenth century for hues that read as continuous and unbroken: a solid blue is one with no variation across the surface. Implies high saturation combined with optical density. Sits in the bold-bucket alongside strong and robust, slightly more focused on uniformity.

Sewn
modifier

Old English sēowan, to-sew. As a color modifier, sewn implies a hand-stitched-and-joined quality, the visual register of hand-sewn-and-stitched-textile hand-needle-and-thread-stitched needle-and-thread-and-bobbin hand-sewn-and-stitched-textile surfaces under hand-sewn-and-stitched-textile workshop-light. Sits at the modifier-and-texture end of the grid, parallel to tied and woven in usage.

Violet
noun

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.

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.
