Electric Andaman

#21bb6a
Notes

Electric Andaman (#21BB6A) 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 (148°, 70%, 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Electric
adjective

From the Greek elektron, amber — the substance whose static-electric properties were observed by Thales of Miletus. Used as a color modifier since the late nineteenth century after electric light made certain saturated colors feel attention-demanding. Electric blue, electric pink: the implication is hot luminance combined with optical impact. Sits at the bright-bucket extreme.

Andaman
noun

The Indian Ocean sea between the Malay Peninsula and the Andaman Islands — and the saturated blue-green of Andaman water at the Surin and Similan island groups. Andaman color refers to mid-depth Andaman Sea water: a saturated, slightly cool deep blue-green with the optical clarity of tropical Asian water.
