Firm Volga

#217cdb
Notes

Firm Volga (#217CDB) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (211°, 74%, 49%) 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.

As a color modifier, firm implies a saturated-and-resolute quality where the hue holds its visual position without wavering. Sits at the bold-and-firm end of the grid, parallel to steadfast and unwavering in usage.

Volga
noun

The Volga River — Europe's longest river, flowing from the Valdai Hills to the Caspian Sea through European Russia. Volga color refers to mid-depth Volga River water at Saratov: a saturated, slightly cool deep blue with the optical depth of major continental river water.
