Royal Sugarcane

#39a521
Notes

Royal Sugarcane (#39A521) 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 (109°, 67%, 39%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Royal
noun

The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.

Sugarcane
noun

Saccharum officinarum, the tropical grass whose stems are pressed for the world's sugar — cultivated since prehistoric times in Papua New Guinea and now grown across the tropical belt. The color refers to fresh sugarcane stalks at harvest: a saturated, slightly cool yellow-green with the satin finish of segmented grass culm.
