Spartan Seth Crimson

#da1f65
Notes

Spartan Seth Crimson (#DA1F65) 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 (338°, 75%, 49%) 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.

Egyptian Set, god-of-storms-and-desert-chaos. As a color modifier, seth implies a desert-storm-and-chaos-god quality, the visual register of Egyptian-Seth-and-Ombos-temple hand-desert-storm-and-chaos-god Egyptian-Seth-and-Ombos-temple-and-Osirian-conflict seth-and-desert-storm-and-chaos-god surfaces under Egyptian-Seth-and-Ombos-temple-and-Osirian-conflict Western-Desert-and-storm-cloud red-desert-storm-light. Sits at the modifier-and-myth end of the grid, parallel to horus and ptah in usage.

Crimson
noun

From the Old Spanish cremesin, itself from the Arabic qirmiz — the kermes scale insect, dried and ground into a brilliant carmine dye prized in the medieval Mediterranean. For centuries the most expensive red on a draper's shelf, reserved for cardinals, kings, and the cloth that gave English the word crimson. Cooler than scarlet, deeper than rose; the color of pomegranate seeds and a serious occasion.

Display P3 representation

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.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
