Sturdy Chambray

#1597d5
Notes

Sturdy Chambray (#1597D5) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (199°, 82%, 46%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Sturdy
adjective

Old French estourdi, stunned, reckless — drifted in English to mean robust, well-built. Used as a color modifier since the seventeenth century for hues that read as durable and unfussy — the working browns of saddle leather, the working greens of pasture wool. Sits in the bold-and-warm corner alongside robust and solid.

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.
