Steady Borage

#378a8a
Notes

Steady Borage (#378A8A) is a true cyan 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 (180°, 43%, 38%) 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 red. 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.

Borage
noun

Borago officinalis, the Mediterranean kitchen herb whose star-shaped blue flowers are edible (used in Pimm's Cup cocktails) and whose leaves taste of cucumber. The color refers to a fresh borage flower at peak bloom: a saturated, slightly cool deep blue with the matte finish of star-shaped Boraginaceae flower.
