Combustive Rarotonga

#2cd499
Notes

Combustive Rarotonga (#2CD499) is a true teal with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (159°, 66%, 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Sits at the bright-and-warm end of the grid, parallel to fiery and blazing in usage.

Rarotonga
