Warm Chambray

#1b7cab
Notes

Warm Chambray (#1B7CAB) 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 (200°, 73%, 39%) 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

Warm
adjective

Old English wearm, of moderate heat — used as a color modifier since the medieval period for hues that read as containing red, orange, or yellow undertones. Warm gray, warm white: not necessarily a temperature, but the optical impression of a slight red-orange shift. Sits across the crisp and neutral buckets.

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.

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.
