Electric Creep Turquoise

#10d3c9
Notes

Electric Creep Turquoise (#10D3C9) is a true cyan with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (177°, 86%, 45%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Electric
adjective

From the Greek elektron, amber — the substance whose static-electric properties were observed by Thales of Miletus. Used as a color modifier since the late nineteenth century after electric light made certain saturated colors feel attention-demanding. Electric blue, electric pink: the implication is hot luminance combined with optical impact. Sits at the bright-bucket extreme.

Creep
modifier

Old English crēopan, to-move-slowly. As a color modifier, creep implies a slow-stealthy-and-spreading quality, the visual register of ivy-on-wall-and-mist-creep hand-slow-stealthy-and-spreading ivy-on-wall-and-mist-creep-and-spreading-shadow crept-and-slow-stealthy-and-spreading surfaces under ivy-on-wall-and-mist-creep-and-spreading-shadow ruined-cloister-and-river-valley-and-evening-meadow encroaching-light. Sits at the modifier-and-mood end of the grid, parallel to lurk and prowl in usage.

Turquoise
noun

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.
