Bluesky Blue
Bluesky Blue (#1185FE) is a true azure 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 (211°, 99%, 53%) 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. The sky-blue of the decentralized social network built on the AT Protocol, spun out of Twitter in 2022. Carried into the 2023 butterfly-logo refresh as the primary brand hue — named for the sky, with no decoding required.
