Rich Savory Ultramarine

#5567c5
Notes

Rich Savory Ultramarine (#5567C5) is a true blue 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 (230°, 49%, 55%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Rich
adjective

Old French riche, wealthy, abundant — applied to color since the medieval period for hues that read as plentiful in pigment. Rich red, rich brown: the implication is depth combined with saturation, a color that gives the eye more to absorb. Sits at the saturated mid-light corner of the engine's grid, slightly warmer than bold and deeper than vivid.

Savory
modifier

Latin satureia, peppery-Mediterranean-herb. As a color modifier, savory implies a peppery-Mediterranean-herb-and-Provençal-bouquet quality, the visual register of Provençal-bouquet-garni-and-summer-savory hand-peppery-Mediterranean-herb-and-Provençal-bouquet Provençal-bouquet-garni-and-summer-savory-and-herbes-de-Provence savory-and-peppery-Mediterranean-herb surfaces under Provençal-bouquet-garni-and-summer-savory-and-herbes-de-Provence Provençal-and-Tuscan-and-Catalan herb-garden-light. Sits at the modifier-and-flavor end of the grid, parallel to hyssop and lovage in usage.

Ultramarine
noun

The pigment ground from lapis lazuli — the Afghan mineral imported through Venice in the late Middle Ages, more expensive by weight than gold during the Renaissance. The color refers to a freshly mixed ultramarine pigment in linseed oil: a saturated, slightly violet-shifted deep blue with the matte finish of micron-ground rock. Deeper than cobalt, cooler than royal, with the art-historical weight of the blue Vermeer reserved for Mary's robe.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
