Steadfast Falun

#ca105b
Notes

Steadfast Falun (#CA105B) 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 (336°, 85%, 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Steadfast
adjective

Old English stede-fæst, fixed in place — sharing root with German stetig. As a color modifier, steadfast implies a saturated-and-unwavering quality where the hue maintains its visual character without modulation. Sits at the bold-and-firm end of the grid, parallel to unwavering and firm in usage.

Falun
noun

The Swedish copper-mining town that gave its name to Falun-red — the iron-oxide paint produced as a byproduct of copper smelting and used to coat almost every wooden Swedish farmhouse since the seventeenth century. The color refers to a freshly painted Falun-red barn: a saturated, slightly muted deep red-brown with the matte finish of clay-and-iron-oxide paint. Drier than maroon, warmer than burgundy.

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.
