Open Padparadscha

#86471f
Notes

Open Padparadscha (#86471F) is a deep orange with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (23°, 62%, 32%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary azure. 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.

Padparadscha
noun

A rare orange-pink variety of sapphire — corundum colored by trace chromium and iron in just the right balance. The name traces to the Sinhalese padma raga, lotus flower. Mined principally in Sri Lanka. The color refers to a faceted padparadscha: a saturated, slightly pink orange with the gem's signature internal life. Cooler than coral.
