Fizzy Cloak Kelly

#34b23b
Notes

Fizzy Cloak Kelly (#34B23B) is a true green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (123°, 55%, 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

Fizzy
adjective

Imitative-onomatopoeic origin — adjectival suffix -y, evoking the sound of carbonation. As a color modifier, fizzy implies a saturated-and-effervescent-and-bubbly quality, the bright color of Champagne-and-Prosecco effervescent-wine carbonation-bubble-light reflection. Sits at the bright-and-effervescent end of the grid, parallel to bubbly and sparkling in usage.

Cloak
modifier

Old Northern French cloque, bell-or-cape. As a color modifier, cloak implies a heavy-shoulder-mantle-and-bell-shaped quality, the visual register of Anglo-Saxon-and-medieval-cloak hand-heavy-shoulder-mantle-and-bell-shaped Anglo-Saxon-and-medieval-cloak-and-pilgrim-cloak cloak-and-heavy-shoulder-mantle surfaces under Anglo-Saxon-and-medieval-cloak-and-pilgrim-cloak Canterbury-and-Compostela-pilgrimage wool-cloak-light. Sits at the modifier-and-textile end of the grid, parallel to cape and cowl in usage.

Kelly
noun

A bright yellow-green named for the Irish surname Kelly, common enough by the late nineteenth century to stand in for generic Irish in American slang. The color is the saturated, optically bright green of a Saint Patrick's Day parade: cleaner than shamrock, brighter than fern, with the pop-culture weight of a color used annually for green beer, green carnations, and the Chicago River.

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.
