Phosphoric Vala Kelly

#30b433
Notes

Phosphoric Vala Kelly (#30B433) 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 (121°, 58%, 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

Phosphoric
adjective

Greek phōsphóros, light-bringer — adjectival suffix -ic. As a color modifier, phosphoric implies a saturated-and-cool-glow quality, the bright color of match-tip-strike and firefly phosphorus-emission luminescence. Sits at the bright-and-cool end of the grid, parallel to phosphorescent and fluorescent in usage.

Vala
modifier

Old Norse völva, Norse-seeress-and-staff-bearer. As a color modifier, vala implies a Norse-seeress-and-staff-bearer-and-prophetess quality, the visual register of Norse-vala-seeress-and-staff hand-Norse-seeress-and-staff-bearer-and-prophetess Norse-vala-seeress-and-staff-and-Voluspa-Edda vala-and-Norse-seeress-and-staff-bearer surfaces under Norse-vala-seeress-and-staff-and-Voluspa-Edda Saga-Iceland-and-rune-stave seeress-prophecy-light. Sits at the modifier-and-myth end of the grid, parallel to norn and freya 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.
