Glowering Eave Ultramarine

Middle English gloweren, to stare angrily — present-participle of glower, sharing root with glower and gloom. As a color modifier, glowering implies a deep-and-warm-and-glowering-resentful quality, the dark warm-orange of furnace-mouth-and-Volcanic-vent embered glow. Sits at the deep-and-warm end of the grid, parallel to smouldered and hellish.

Old English efes, roof-edge. As a color modifier, eave implies a roof-overhang-and-edge quality, the visual register of Japanese-engawa-and-English-eave hand-built roof-overhang-and-edge eave-and-fascia-and-soffit architectural surfaces under Japanese-and-English eave-edge filtered light. Sits at the modifier-and-architecture end of the grid, parallel to gable and frieze 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.
