Pellucid Udaipur

#686bbd
Notes

Pellucid Udaipur (#686BBD) is a true blue 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 (238°, 39%, 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Pellucid
adjective

Latin pellūcidus, transparent — derived from per-lūcēre (to shine through). As a color modifier, pellucid implies a clear-and-translucent quality where the hue reads with optical clarity and minimal turbidity. Sits at the crisp-and-clear end of the grid, parallel to lucid and translucent in usage.

Udaipur
noun

The Rajput City of Lakes in Mewar, Rajasthan — home of the Mewar court whose miniature paintings used ultramarine (powdered Afghan lapis) and indigo for the deep skies and royal robes. Udaipur color refers to a Mewar-school 17th-century miniature's lapis-and-indigo sky field: a saturated, slightly cool deep blue-violet with the matte finish of mineral ultramarine on hand-prepared vasli paper.
