Phosphoric Guacamole
Phosphoric Guacamole (#99C040) is a true lime 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 (78°, 50%, 50%) 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
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.
The Mexican avocado-based dip — fresh avocado mashed with lime, cilantro, salsa, and salt, traced to pre-Columbian Aztec cuisine via the Nahuatl āhuacamolli (avocado sauce). Guacamole color refers to fresh-mashed guacamole in a molcajete: a soft, slightly muted yellow-green with the matte finish of pureed avocado-and-lime. Drier than avocado.
