Tucked Bothnia

#81eef5
Notes

Tucked Bothnia (#81EEF5) is a soft cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (184°, 85%, 73%) places it in the highly saturated band at a light 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

Tucked
adjective

Old English tūcian, to torment / pull — past-participle of tuck. As a color modifier, tucked implies a clear-and-fitted-and-arranged quality where the hue carries the visual register of carefully-tucked-and-neatly-fitted shirt-into-trouser dress-attire. Sits at the crisp-and-finished end of the grid, parallel to trim and pressed 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.
