Mighty Yangtze

#0d8aee
Notes

Mighty Yangtze (#0D8AEE) 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%, 49%) 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

Mighty
adjective

Old English mihtig, strong — adjectival suffix -y, sharing root with German mächtig. As a color modifier, mighty implies a saturated-and-strong-presence quality, where the hue commands visual attention through pure pigmentation strength. Sits at the bold-and-saturated end of the grid, parallel to forceful and commanding in tone.

Yangtze
noun

The Chinese Cháng Jiāng — the longest river in Asia and the third-longest in the world. Yangtze color refers to mid-depth Yangtze River water at the Three Gorges: a saturated, slightly cool deep blue with the optical complexity of glacier-fed Tibetan-Plateau-source river water.
