Heartening Phuket

#64c081
Notes

Heartening Phuket (#64C081) is a true green 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 (139°, 42%, 57%) 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

Heartening
adjective

Old English heorte (heart) — present-participle of hearten. As a color modifier, heartening implies a clear-and-uplifting-and-encouraging quality where the hue carries the visual register of cheerful-encouraging color-tone. Sits at the crisp-and-cheerful end of the grid, parallel to welcoming and cheerful in usage.

Phuket
noun

The Thai island in the Andaman Sea — and the saturated turquoise of Phuket's western beach water at Patong and Karon. Phuket refers to the beach water at midday: a saturated, slightly cool deep blue-green with the optical clarity of warm tropical-Asian water.
