Buoyant Polar

#b9d8d5
Notes

Buoyant Polar (#B9D8D5) is a soft teal with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (174°, 28%, 79%) places it in the muted band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. 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

Buoyant
adjective

Old French boie, floating — adjectival suffix -ant. As a color modifier, buoyant implies a pale-and-floating-and-lifted quality where the hue carries the visual register of cork-and-balloon-rising-and-floating spatial-and-mood weightless-feel. Sits at the pale-and-soft end of the grid, parallel to floaty and floating in usage.

Polar
noun

Of the polar — the ice caps and the meltwater seas at the high latitudes. The color refers to polar sea ice on a clear day at the height of summer melt: a soft, slightly green-shifted very pale blue with the optical brightness of bubble-rich ice. Lighter than glacier, cooler than frost, with the climatological weight of a region whose color is rapidly disappearing.
