Splashy Estuary

#57cf87
Notes

Splashy Estuary (#57CF87) 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 (144°, 56%, 58%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Splashy
adjective

Imitative-onomatopoeic origin — adjectival suffix -y, evoking the sound of liquid impact. As a color modifier, splashy implies a saturated-and-attention-grabbing-and-bold quality, the bright color of Pop-Art-and-1950s-Tiki mid-century-modern showy-decor advertising-and-display. Sits at the bright-and-flamboyant end of the grid, parallel to showy and flamboyant in usage.

Estuary
noun

The mixing zone where freshwater rivers meet saltwater seas — the Chesapeake, the Thames, the Hudson — environments of unique salinity and biodiversity. Estuary color refers to mid-depth estuary water at high tide: a soft, slightly cool deep blue-green with the optical complexity of brackish water.
