Forthright Throne Ultramarine

#0940ad
Notes

Forthright Throne Ultramarine (#0940AD) is a true azure with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (220°, 90%, 36%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Forthright
adjective

Old English forð-riht, straight ahead, direct. Used as a color modifier in Anglo-Saxon-revival contexts for hues that read as honest and unguarded. Forthright red, forthright blue: the saturation is full, the hue is presented without ornamentation or qualification. Sits in the bold-bucket center alongside frank and direct.

Throne
modifier

Latin thronus, seat-of-state. As a color modifier, throne implies a king-and-queen-ceremonial-seat quality, the visual register of Russian-Imperial-and-Tudor-Court hand-carved jeweled-and-gilt-and-velvet ceremonial-seat-of-state surfaces under Russian-Imperial-Romanov-and-Tudor-Court hand-carved ceremonial-seat candlelight. Sits at the modifier-and-cultural end of the grid, parallel to crown and manor 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.

Wide gamut

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.
