Composed Anchor

#6439d2
Notes

Composed Anchor (#6439D2) is a true indigo 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 (257°, 63%, 52%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Composed
adjective

The past participle of compose, to arrange together — used as a color modifier for hues that read as deliberate and balanced. Composed black, composed gray: the saturation is moderate, the hue is calmly positioned without aggression. Sits at the bold-and-quiet edge of the grid near settled and resolute.

Anchor
noun

The maritime and military attribute — the metal hook that holds a vessel to the bottom — and the deep blue color named after the dark wool dyed for British and American naval anchor crews. The color refers to an anchor-blue dyed wool: a saturated, slightly muted deep blue with the matte finish of heavyweight wool. Cooler than navy, warmer than midnight, with the maritime weight of a working-blue distinct from the dress-blue of officer ranks.

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.
