Inflamed Sunbird

#66a627
Notes

Inflamed Sunbird (#66A627) is a true lime 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 (90°, 62%, 40%) 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

Inflamed
adjective

Latin inflammātus, set on fire — past-participle of inflame. As a color modifier, inflamed implies a saturated-and-irritated-hot quality, the bright color of sun-burnt-skin and autumn-leaf high-anthocyanin pigmentation. Sits at the bright-and-warm end of the grid, parallel to fiery and flaming in usage.

Sunbird
noun

The family Nectariniidae — Old World sunbirds, the ecological equivalent of New World hummingbirds. Particularly Cinnyris jugularis (olive-backed sunbird) whose iridescent green throat catches direct sunlight. The color refers to a male sunbird's gorget: a saturated, slightly cool deep green with the iridescent satin finish of structural color.
