Anchored Alizarin

#b3318e
Notes

Anchored Alizarin (#B3318E) is a true magenta with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (317°, 57%, 45%) 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

Anchored
adjective

The past participle of anchor, used since the late nineteenth century as a metaphor for secured in place. As a color word, anchored implies a deep saturated tone that grounds a palette — the dark blues, deep greens, and browns that hold a composition together. Sits in the bold-and-deep corner of the grid alongside solid.

Alizarin
noun

1,2-dihydroxyanthraquinone — the principal anthraquinone dye component of madder root (Rubia tinctorum), first isolated and synthesized in 1869 by Carl Graebe and Carl Liebermann. Alizarin color refers to a freshly alizarin-mordant-dyed wool: a saturated, slightly cool deep magenta with the matte finish of anthraquinone-dye-on-mordanted woolen fiber. The first natural pigment to be replaced by a synthetic.

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.
