Lined Chambray

#63b1db
Notes

Lined Chambray (#63B1DB) 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 (201°, 62%, 62%) 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

Lined
adjective

Old English līne, line / cord — past-participle of line. As a color modifier, lined implies a clear-and-coordinated-and-supported quality where the hue carries the visual register of carefully-lined-and-supported textile-or-print surface. Sits at the crisp-and-finished end of the grid, parallel to trim and coordinated 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.

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.
