Plumb Pepper Turquoise

#54d9c6
Notes

Plumb Pepper Turquoise (#54D9C6) is a true teal with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (171°, 64%, 59%) 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.

Pepper
modifier

Latin piper, black-pepper-corn. As a color modifier, pepper implies a black-pepper-corn-and-Malabar-Coast quality, the visual register of Malabar-Coast-and-Vietnamese-pepper hand-black-pepper-corn-and-Malabar-Coast Malabar-Coast-and-Vietnamese-pepper-and-Tellicherry pepper-and-black-pepper-corn surfaces under Malabar-Coast-and-Vietnamese-pepper-and-Tellicherry Malabar-and-Tellicherry-and-Phu-Quoc Indian-Ocean-spice-light. Sits at the modifier-and-flavor end of the grid, parallel to clove and cumin 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.
