Devout Mekong

#1d59a0
Notes

Devout Mekong (#1D59A0) is a true azure 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 (213°, 69%, 37%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Devout
adjective

From the Latin devotus, consecrated — used principally in religious contexts for the dignified deep colors of sacred art and ecclesiastical dress. As a color modifier, devout implies saturation combined with restraint: the deep blues of Marian mantles, the deep reds of cardinals' robes. Sits in the bold-and-formal corner alongside imperial.

Mekong
noun

The Southeast Asian river flowing from the Tibetan Plateau through China, Burma, Laos, Thailand, Cambodia, and Vietnam. Mekong color refers to mid-depth Mekong River water at Luang Prabang in Laos: a saturated, slightly cool deep blue-brown with the optical complexity of monsoon-fed silty river water.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
