Welcoming Bluff Kingfisher

#36cdb7
Notes

Welcoming Bluff Kingfisher (#36CDB7) is a true teal 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 (171°, 60%, 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

As a color modifier, bluff implies a high-river-bank quality, the visual register of Mississippi-and-Missouri-River-Bluffs tall sediment-and-loess river-bank cliff-face surfaces in late-afternoon Mississippi-and-Missouri-River raking light. Sits at the modifier-and-place end of the grid, parallel to cliff and crag in usage.

Kingfisher
noun

The family Alcedinidae — particularly Alcedo atthis, the European common kingfisher whose iridescent turquoise-blue plumage gives the color its name.
