True Volgograd

#138ff3
Notes

True Volgograd (#138FF3) is a true azure with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (207°, 90%, 51%) 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

True
adjective

Old English trēowe, faithful — used as a color modifier since the seventeenth century for hues that read as the canonical version of their family. True red, true blue: the saturation is full, the hue is neither shifted nor adulterated. Sits at the center of the bold and crisp buckets, marking the unequivocal middle of any chromatic family.

Volgograd
noun

The Russian city on the Volga River (formerly Stalingrad) — and the deep blue of the Volga River and the surrounding steppe sky. Volgograd refers to mid-depth Volga River water: a saturated, slightly cool deep blue with the optical complexity of major continental river water.
