Refreshing Zenith Turquoise

Old French refreschir, to make fresh again — present-participle of refresh.

Sits at the crisp-and-cool end of the grid, parallel to fresh and bracing in usage.

Sits at the modifier-and-cosmic end of the grid, parallel to nadir and axis 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.
