Stamped Pineapple

#637b21
Notes

Stamped Pineapple (#637B21) is a deep lime 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 (76°, 58%, 31%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Stamped
adjective

Old English stempan, to stamp — past-participle of stamp. As a color modifier, stamped implies a clear-and-impressed-and-repeating quality, the crisp color of William-Morris-and-Liberty-of-London block-printed-textile carefully-impressed pattern. Sits at the crisp-and-printed end of the grid, parallel to printed and engraved in usage.

Pineapple
noun

Ananas comosus, the cultivated pineapple — domesticated in the Caribbean and South America by the Tupí and a luxury good of seventeenth-century European glasshouses, where a single fruit could cost the equivalent of thousands of dollars. The color refers to a ripe pineapple's flesh: a clean, slightly translucent gold-yellow that's brighter than honey and softer than canary, with the optical brightness of high-water-content tropical fruit.

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.
