Welcoming Fjord

#309d8f
Notes

Welcoming Fjord (#309D8F) 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 (172°, 53%, 40%) 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.

Fjord
noun

The deep glacier-carved coastal inlets of Norway, Iceland, New Zealand, and Patagonia — formed during the Pleistocene as ice sheets retreated and seawater flooded the glacial valleys. Fjord color refers to mid-depth Norwegian fjord water at Geirangerfjord: a deep, slightly cool deep blue-green with the optical complexity of glacier-melt water mixed with cold seawater.
