Conquering Pegasus Ultramarine

#3964d1
Notes

Conquering Pegasus Ultramarine (#3964D1) is a true azure 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 (223°, 62%, 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Conquering
adjective

Latin conquīrere, to seek thoroughly — present-participle of conquer. As a color modifier, conquering implies a saturated-and-overwhelming-and-victorious quality where the hue overcomes neighboring colors through pure pigmentation strength. Sits at the bold-and-celebratory end of the grid, parallel to triumphant and dominant.

Pegasus
modifier

Greek Πήγασος, winged-horse-of-myth. As a color modifier, pegasus implies a winged-horse-and-Great-Square quality, the visual register of Pegasus-Great-Square-and-winged-horse hand-winged-horse-and-Great-Square Pegasus-Great-Square-and-winged-horse-and-autumn-Pegasus pegasus-and-winged-horse-and-Great-Square surfaces under Pegasus-Great-Square-and-winged-horse-and-autumn-Pegasus October-and-November-autumn-zenith autumn-constellation-light. Sits at the modifier-and-cosmic end of the grid, parallel to cygnus and draco 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.
