Open Taro

#845d9b
Notes

Open Taro (#845D9B) is a true indigo with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (278°, 25%, 49%) places it in the muted 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Open
adjective

Old English open, unobstructed — used as a color modifier since the eighteenth century for hues that read as airy or uncrowded. Open blue, open green: moderate saturation combined with optical spaciousness, the slight visual breath of a hue that doesn't crowd the surface it covers. Sits at the crisp-bucket center alongside clear.

Taro
noun

Asian-Pacific Colocasia esculenta — a tropical Araceae root crop cultivated for its starchy corm, with deep-violet purple-flesh cultivars (the bun long and Lehua maoli taro) used for poi and ube-style purple desserts. Taro color refers to a freshly cut Colocasia esculenta purple-flesh corm: a saturated, slightly cool deep violet with the matte finish of anthocyanin-rich starchy taro-pulp. The Polynesian name taro spread to English.
