Blanched Bothnia

#83adb1
Notes

Blanched Bothnia (#83ADB1) is a true 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 (185°, 23%, 60%) places it in the muted 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Blanched
adjective

French blanchir, to whiten — past-participle of blanch. As a color modifier, blanched implies a pale-and-bleached-and-whitened quality, the pale color of Provençal-cuisine briefly-boiled-and-cold-shocked vegetable color-shift surface. Sits at the pale-and-bleached end of the grid, parallel to bleached and whitened 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.
