Submersed Watercress

#1b3309
Notes

Submersed Watercress (#1B3309) is a deep lime 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 (94°, 70%, 12%) 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

Submersed
adjective

Latin sub-mersus, plunged-under — past-participle of submerse. As a color modifier, submersed implies the deep-saturated-and-cool-shifted quality of a hue viewed through a layer of water, like an underwater coral-reef object seen from a glass-bottomed boat. Sits at the deep-and-cool end of the grid, parallel to submerged with slightly-archaic register.

Watercress
noun

Nasturtium officinale, the European aquatic mustard-family green eaten in soups, salads, and sandwiches — particularly in the celebrated cresson de fontaine of French bouquet garni. Watercress color refers to fresh-picked watercress in cool stream water: a saturated, slightly cool deep yellow-green with the satin finish of aquatic-leaf surface. Cooler than arugula.
