Punchy Bothnia

#18bbea
Notes

Punchy Bothnia (#18BBEA) 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 (193°, 83%, 51%) 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

Punchy
adjective

A modern adjectival form of punch, to strike sharply. Used as a color word since the early twentieth century for hues that read as highly contrasting and visually loud. Punchy red, punchy yellow: the implication is full saturation combined with optical impact. Sits across the bold and bright buckets, near vivid and striking.

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.

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.
