Plainspoken Tide

#27d1df
Notes

Plainspoken Tide (#27D1DF) 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 (185°, 74%, 51%) 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.

Tide
noun

The slow flow of seawater driven by lunar gravity — the daily cycle of high to low and back. Tidal and tide used as a color refer to the deep blue-green of coastal water at mid-tide on an overcast day: a soft, slightly muted blue-green with the optical complexity of water in motion. Cooler than reef, deeper than seafoam, with the ecological weight of a force that has shaped every coastline on Earth.

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.
