Stalwart Sidon

#ac39c4
Notes

Stalwart Sidon (#AC39C4) is a true violet with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (290°, 55%, 50%) 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

Stalwart
adjective

Old English stǣl-wyrðe, stable-and-worthy. As a color modifier, stalwart implies a saturated-and-loyal-and-firm quality where the hue carries the dependable-and-trustworthy visual presence of a Knight-Templar guard. Sits at the bold-and-firm end of the grid, parallel to steadfast and firm in usage.

Sidon
noun

Ancient Phoenician city on the Lebanese coast — co-eval with Tyre in Tyrian purple production, and the slightly older of the two purple-dye centers. Sidon color refers to a Sidon-produced Tyrian purple-dyed Phoenician trade textile: a saturated, slightly cool deep violet with the matte finish of multi-bath Hexaplex trunculus shellfish dye on hand-loomed Levantine cloth.

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.
