Placid Chambray

#6695b3
Notes

Placid Chambray (#6695B3) is a true azure 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 (203°, 34%, 55%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Placid
adjective

Latin placidus, gentle / quiet — derived from placēre (to please). As a color modifier, placid implies a clear-and-unruffled quality where the hue carries the visual register of mirror-smooth lake-surface in windless mid-morning. Sits at the crisp-and-calm end of the grid, parallel to serene and peaceful in usage.

Chambray
noun

A lightweight cotton fabric woven with a colored warp and white weft — producing a soft chambray-blue characteristic of summer workwear and cambric dressmaking. The color refers to a freshly woven chambray shirt before any wash: a soft, slightly muted deep blue with the satin finish of fine cotton-and-indigo weave.
