Straightforward Yangtze

#5b6c89
Notes

Straightforward Yangtze (#5B6C89) is a true azure 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 (218°, 20%, 45%) places it in the muted 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Straightforward
adjective

English compound straight + forward — sharing root with German geradeaus. As a color modifier, straightforward implies a clear-and-direct-and-unencumbered quality where the hue carries the visual register of clear-aim-and-uncomplicated character. Sits at the crisp-and-honest end of the grid, parallel to candid and direct in usage.

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.
