Balanced Tarn

#63eeea
Notes

Balanced Tarn (#63EEEA) is a true cyan 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 (178°, 80%, 66%) 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 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.

Tarn
noun

A small mountain lake — particularly the cwm (cirque) lakes of the British Lake District, the Welsh hills, and the Norwegian peaks. From the Old Norse tjörn. Tarn color refers to a fresh-water tarn at Stickle Tarn in Cumbria: a saturated, slightly cool deep blue with the optical depth of cold-water mountain pool.
