Resolute Crimea

#2a57d5
Notes

Resolute Crimea (#2A57D5) 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 (224°, 67%, 50%) 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

Resolute
adjective

From the Latin resolutus, unwavering — used as a color modifier in literary contexts for hues that read as committed and unmoving. Resolute blue, resolute green: the saturation is full, the hue holds its position without shifting under different light. Sits in the bold-bucket center alongside strong and true, with slightly more focus on stability than presence.

Crimea
noun

The Black Sea peninsula — and the saturated deep blue of the Black Sea coast at Yalta and Sevastopol. Crimea refers to the Black Sea off the Yalta coastline at midday: a saturated, slightly cool deep blue with the optical depth of brackish enclosed-sea water.
