Pulsing Era Turquoise

The progressive participle of pulse, to throb. Used as a color modifier for hues that read as if they were alternating between two states of luminance — the vibration of a high-saturation color against a contrasting background. Sits in the bright-bucket center alongside electric, with the implication of optical motion rather than static luminance.

Latin aera, epoch. As a color modifier, era implies a period-and-historical-epoch quality, the visual register of historical-period-and-epoch multi-decade period-correct epoch-marked-and-defining-period surfaces under historical-period epoch-defining mood-and-light. Sits at the modifier-and-time end of the grid, parallel to age and cycle 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.
