Energetic Watercress

#5bb82d
Notes

Energetic Watercress (#5BB82D) 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 (100°, 61%, 45%) 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

Energetic
adjective

Greek energētikós, active — derived from energeia (activity). As a color modifier, energetic implies a saturated-and-kinetic-and-active quality where the hue carries visual vibration and movement-suggestion that engages the eye dynamically. Sits at the bright-and-active end of the grid, parallel to dynamic and spirited in usage.

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.

Wide gamut

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.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
