Hefty Sequoia

#289637
Notes

Hefty Sequoia (#289637) is a true green 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 (128°, 58%, 37%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Hefty
adjective

Old English hefig, heavy — adjectival suffix -y. As a color modifier, hefty implies a saturated-and-substantial-and-weighty quality where the hue carries the visual heft of a hand-cast pig-iron object. Sits at the bold-and-weighty end of the grid, parallel to substantial and weighty in usage.

Sequoia
noun

Sequoiadendron giganteum, the giant sequoia of the Sierra Nevada — the largest living tree species on Earth by volume. Sequoia color refers to mature sequoia needle foliage: a deep, slightly cool dark green with the matte finish of scale-leaf conifer foliage.

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.
