Welcoming Tideway

#7cdce1
Notes

Welcoming Tideway (#7CDCE1) 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 (183°, 63%, 68%) 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

Welcoming
adjective

Old English wel-cuman, well-coming — present-participle of welcome. As a color modifier, welcoming implies a clear-and-inviting-and-warm quality where the hue carries the visual register of cordial-and-hospitable color-tone. Sits at the crisp-and-cheerful end of the grid, parallel to hospitable and inviting in usage.

Tideway
noun

A tidal river channel — particularly the tidal Thames between London Bridge and Teddington Lock, the historical Tideway of London's Thames-side commerce. Tideway color refers to mid-tide Thames at Greenwich on a clear day: a soft, slightly cool deep blue-green with the optical complexity of tidal-mixed brackish water.

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.
