Wholesome Catnip Turquoise

#31b2c6
Notes

Wholesome Catnip Turquoise (#31B2C6) is a true cyan 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 (188°, 60%, 48%) 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

Wholesome
adjective

An adjectival form of whole — used as a color modifier since the sixteenth century for hues that read as healthy and unadulterated. Wholesome cream, wholesome wheat: moderate saturation combined with the optical impression of a natural origin. Sits at the crisp-bucket alongside genuine.

Catnip
modifier

Old English catte-nepe, cat-mint-or-catnip. As a color modifier, catnip implies a cat-mint-and-grey-green-cottage-herb quality, the visual register of English-cottage-and-Quaker-herb-garden-catnip hand-cat-mint-and-grey-green-cottage-herb English-cottage-and-Quaker-herb-garden-catnip-and-Tudor-still-room catnip-and-cat-mint surfaces under English-cottage-and-Quaker-herb-garden-catnip-and-Tudor-still-room Sussex-cottage-and-New-England-Quaker-garden cottage-herb-light. Sits at the modifier-and-flavor end of the grid, parallel to hyssop and lovage 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.
