Clear Gloom Turquoise

From the Latin clarus, bright, distinct — used as a color modifier since the medieval period for hues without haze or mixing. Clear blue sky, clear green water: the implication is moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clean and true.

Middle English gloumen, to-look-sullen. As a color modifier, gloom implies a sullen-and-darkened-and-overcast quality, the visual register of Northumbrian-moor-and-Scottish-glen-gloom hand-sullen-and-darkened-and-overcast Northumbrian-moor-and-Scottish-glen-and-Yorkshire-dale gloomed-and-darkened-and-overcast surfaces under Northumbrian-moor-and-Scottish-glen overcast-and-low-cloud heather-and-bracken-light. Sits at the modifier-and-mood end of the grid, parallel to murk and drear in usage.

The hydrated copper-aluminum phosphate mined in Persia and the American Southwest for thousands of years — the firuze of Iran, the chalchihuitl of Mesoamerica, the heart of Pueblo and Navajo silverwork. The color refers to a fine Sleeping Beauty turquoise from Arizona: a saturated, slightly green-shifted blue with the slight matrix of host-rock veining. Brighter than persian, lighter than cerulean.
