Plainspoken Polar

#308e85
Notes

Plainspoken Polar (#308E85) is a true teal with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (174°, 49%, 37%) places it in the balanced 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

Plainspoken
adjective

English compound plain + spoken — past-participle of speak. As a color modifier, plainspoken implies a clear-and-direct-and-straightforward quality where the hue carries the visual register of unembellished-honest declaration. Sits at the crisp-and-honest end of the grid, parallel to candid and direct 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.

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.
