Neat Bothnia

#51e7eb
Notes

Neat Bothnia (#51E7EB) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (182°, 79%, 62%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Neat
adjective

Old French net, clean / pure — sharing root with Latin nitidus. As a color modifier, neat implies a clear-and-orderly quality where the hue carries the well-arranged visual register without clutter or excess. Sits at the crisp-and-orderly end of the grid, parallel to trim and tidy in usage.

Bothnia
noun

The Gulf of Bothnia — the northernmost arm of the Baltic Sea between Sweden and Finland. Bothnia color refers to mid-depth Gulf of Bothnia water at midsummer: a saturated, slightly cool deep blue with the optical complexity of low-salinity high-latitude brackish water.
