Firm Crimea

#2a81fb
Notes

Firm Crimea (#2A81FB) is a true azure with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (215°, 96%, 57%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Firm
adjective

Latin firmus, strong / stable — sharing root with English farm (originally a fixed-yearly-rental). 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.

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.
