Vivid Aozora

#2a9eed
Notes

Vivid Aozora (#2A9EED) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (204°, 84%, 55%) 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

Vivid
adjective

From the Latin vividus, full of life — used as a color modifier since the late sixteenth century for hues that read as luminous and saturated. Vivid red, vivid blue: the implication is that the color appears almost lit from within, with the optical brightness of a high-chroma surface in good light. Sits at the bright-bucket center alongside bright and electric.

Aozora
noun

The Japanese compound for blue sky — used for the high-saturation deep blue of cloudless mid-day sky. Aozora names the brand of children's literacy programs in modern Japan and the literary association of clarity. The color refers to a Tokyo summer aozora at midday: a saturated, slightly cool deep blue with the optical brightness of clean atmosphere.
