Balanced Woad

#66e3de
Notes

Balanced Woad (#66E3DE) 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 (178°, 69%, 65%) 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

Balanced
adjective

The past participle of balance, to weigh evenly. Used as a color modifier since the eighteenth century for hues that read as neither overcommitted nor restrained. Balanced sage, balanced taupe: moderate saturation combined with optical equilibrium. Sits at the crisp-bucket center alongside even.

Woad
noun

Isatis tinctoria, the European blue-dye plant whose leaves yield indigo-equivalent indigotin. Used by Pictish warriors as body paint and the dominant pre-industrial European blue dye until East Indian indigo displaced it in the seventeenth century. The color refers to a freshly woad-dyed wool: a saturated, slightly cool deep blue with the matte finish of plant-and-mordant dye.
