Replete Sash Ultramarine

#4369c1
Notes

Replete Sash Ultramarine (#4369C1) 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 (222°, 50%, 51%) 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

Replete
adjective

Latin replētus, filled — past-participle of replēre. As a color modifier, replete implies a saturated-and-fully-pigmented quality where the hue is completely loaded with its source pigment. Sits at the bold-and-saturated end of the grid, parallel to brimming and suffused in usage.

Sash
modifier

Arabic shāsh, muslin-strip-or-turban-cloth. As a color modifier, sash implies a wound-strip-and-cummerbund-and-bandolier quality, the visual register of Mughal-cummerbund-and-Spanish-fajín-sash hand-wound-strip-and-cummerbund-and-bandolier Mughal-cummerbund-and-Spanish-fajín-sash-and-Ottoman-sash sash-and-wound-strip-and-cummerbund surfaces under Mughal-cummerbund-and-Spanish-fajín-sash-and-Ottoman-sash Mughal-Delhi-and-Iberian-and-Ottoman-Topkapi wound-cloth-light. Sits at the modifier-and-textile end of the grid, parallel to kilt and shawl 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.
