True Inca Jade

#04ac91
Notes

True Inca Jade (#04AC91) is a true teal with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (170°, 95%, 35%) 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

True
adjective

Old English trēowe, faithful — used as a color modifier since the seventeenth century for hues that read as the canonical version of their family. True red, true blue: the saturation is full, the hue is neither shifted nor adulterated. Sits at the center of the bold and crisp buckets, marking the unequivocal middle of any chromatic family.

Inca
modifier

Quechua Inka, prince. As a color modifier, inca implies a Cuzco-and-Andean-Imperial quality, the visual register of Inca-Empire hand-cut stone-and-textile-and-quipu Inca-Imperial Andean-Highland and-Sapa-Inca surfaces under high-altitude Inca-Empire Cuzco-and-Machu-Picchu Andean-Highland light. Sits at the modifier-and-cultural end of the grid, parallel to aztec and toltec in usage.

Jade
noun

Two minerals share the name: nephrite (a calcium-magnesium silicate, dominant in Chinese jade) and jadeite (a sodium-aluminum silicate, dominant in Burmese imperial jade). Both have been carved in China since at least the Neolithic. The color refers to high-quality apple-green jadeite: a saturated, slightly muted yellow-green with the waxy translucency of polished stone. Cooler than apple, warmer than mint, with the millennial cultural weight of yu, the stone of heaven.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

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.
