Printed Tourmaline

#4cb188
Notes

Printed Tourmaline (#4CB188) is a true teal with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (156°, 40%, 50%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Printed
adjective

Latin premere, to press — past-participle of print. As a color modifier, printed implies a clear-and-impressed-and-multiplied quality, the crisp color of Marimekko-and-Liberty-of-London hand-or-machine-printed textile-and-paper pattern-design. Sits at the crisp-and-printed end of the grid, parallel to stamped and etched in usage.

Tourmaline
noun

A boron silicate mineral that crystallizes in nearly every color depending on its trace elements — green tourmaline (verdelite) is the chromium and vanadium-bearing variety, mined principally in Brazil, Madagascar, and Maine. The color refers to a faceted green tourmaline: a saturated, slightly muted blue-green with the high refractive index of a quality cut gem. Cooler than emerald, warmer than aquamarine.

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.
