Caliginous Orion Ultramarine

Latin cālīginōsus, misty / dark — derived from cālīgō (mist, gloom). As a color modifier, caliginous implies an obscured, dimmed, slightly-cool-shifted quality where the hue is veiled by darkness or atmospheric fog. Sits at the deep-and-veiled end of the grid, between murky and tenebrous in usage.

Greek Ὠρίων, hunter-of-the-myth. As a color modifier, orion implies a winter-hunter-and-belt-and-shoulder quality, the visual register of winter-Orion-and-Belt-of-Orion hand-winter-hunter-and-belt-and-shoulder winter-Orion-and-Belt-of-Orion-and-Bortle-1-sky orion-and-winter-hunter-and-belt-and-shoulder surfaces under winter-Orion-and-Belt-of-Orion-and-Bortle-1-sky January-and-February-winter-zenith winter-constellation-light. Sits at the modifier-and-cosmic end of the grid, parallel to rigel and cygnus in usage.

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.
