Steady Bay

#315870
Notes

Steady Bay (#315870) is a deep azure with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (203°, 39%, 32%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Steady
adjective

Old English stede, place, position — drifted to mean firm and unmoving. Used as a color modifier since the seventeenth century for hues that read as reliable rather than dramatic. Steady gray, steady green: moderate saturation combined with optical calmness. Sits in the crisp-bucket center alongside settled.

Bay
noun

A body of water partially enclosed by land — Chesapeake, Tokyo, Hudson, Naples. The color refers to the average reflectance of a temperate bay on a clear day: a saturated, slightly muted blue with the optical depth of mid-salinity water. Cooler than peacock, warmer than navy, with the geographic specificity of a word that names the largest indentations in every world coastline.
