Steady Wakatake

#66d39b
Notes

Steady Wakatake (#66D39B) is a true teal 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 (149°, 55%, 61%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Steady
adjective

Old English stede, place, position — drifted to mean firm and unmoving. Used as a color modifier since the seventeenth century for hues that read as reliable rather than dramatic. Steady gray, steady green: moderate saturation combined with optical calmness. Sits in the crisp-bucket center alongside settled.

Wakatake
noun

Japanese for young bamboo — and the soft blue-green of fresh Phyllostachys shoots before they mature to aotake. Wakatake-iro signals seasonal renewal in Japanese textile vocabulary. The color refers to a young bamboo shoot in spring: a soft, slightly cool yellow-green-blue with the satin finish of fresh culm. Lighter than aotake.
