Combustive Vine

#63b524
Notes

Combustive Vine (#63B524) is a true lime with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (94°, 67%, 43%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Combustive
adjective

Latin combūstus, burnt — adjectival suffix -ive, derived from com-burere (to burn-up). As a color modifier, combustive implies a saturated-and-burning-active quality, the bright color of blast-furnace-and-foundry combustion-chamber emission. Sits at the bright-and-warm end of the grid, parallel to fiery and blazing in usage.

Vine
noun

Generic for any climbing plant — particularly the grapevine Vitis vinifera whose leaves are central to Mediterranean wine viticulture and dolma cooking. Vine color refers to fresh grape-vine leaves in early summer: a saturated, slightly cool deep yellow-green with the matte finish of vine leaf surface.

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.
