Plumb Blaze Turquoise

#1bb6c1
Notes

Plumb Blaze Turquoise (#1BB6C1) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (184°, 75%, 43%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Plumb
adjective

Latin plumbum, lead — referring to the lead-weighted plumb-line of pre-modern carpentry. As a color modifier, plumb implies a clear-and-vertical-true quality where the hue carries the visual register of gravity-aligned-and-perfectly-vertical surface. Sits at the crisp-and-balanced end of the grid, parallel to level and squared in usage.

Blaze
modifier

Old English blæse, torch-or-flame. As a color modifier, blaze implies a roaring-and-bright-and-spreading-flame quality, the visual register of bonfire-and-Yule-log-blaze hand-roaring-and-bright-and-spreading-flame bonfire-and-Yule-log-and-hearth-fire blazed-and-roaring-and-bright-and-spreading surfaces under bonfire-and-Yule-log-and-hearth-fire roaring-and-bright-and-spreading midwinter-and-bonfire-night-light. Sits at the modifier-and-mood end of the grid, parallel to flare and spark 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
