Cleansed Indranīla

#577cb3
Notes

Cleansed Indranīla (#577CB3) is a true azure 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 (216°, 38%, 52%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Cleansed
adjective

Old English clǣnsian, to make clean — past-participle of cleanse. As a color modifier, cleansed implies a clear-and-purified quality where the hue has been stripped of any contaminating tint. Sits at the crisp-and-clear end of the grid, parallel to fresh and pristine in usage.

Indranīla
noun

The Sanskrit word for sapphire — combining Indra (the king of the gods) and nīla (deep blue). Used in classical Hindu jewelry vocabulary for the deep-blue gems of Indian royal regalia. The color refers to a faceted Kashmir indranīla: a saturated, slightly cool deep blue with the gem's signature internal velvet.
