Ironclad Atriplex

#158545
Notes

Ironclad Atriplex (#158545) is a deep 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 (146°, 73%, 30%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Ironclad
adjective

English compound iron + clad — referring to the 19th-century USS-Monitor and CSS-Virginia iron-armored warships. As a color modifier, ironclad implies a saturated-and-armored-and-impenetrable quality where the hue carries the visual weight of forged-iron armor-plate. Sits at the bold-and-fortified end of the grid, parallel to fortified and armored.

Atriplex
noun

The genus Atriplex — saltbushes, the salt-tolerant gray-green shrubs of saline desert, beach, and salina habitats from California to Australia. The color refers to a clump of A. canescens in Mojave Desert: a soft, slightly cool silver-green with the matte finish of salt-encrusted leaf.

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.
