LinkedIn has always lived in this family of medium-dark blue. It reads as professional without feeling as cold as some enterprise software palettes, and the off-white feed background adds just enough warmth to distinguish it from starker competitors.
LinkedIn Blue (#0A66C2) has gone through multiple iterations since the platform launched in 2003, but it's always stayed in this family of medium-to-bold corporate blue. The current shade is rich enough to project authority but not so dark that it feels heavy. It pairs naturally with white for a clean, readable feed. The background gray (#F3F2EF) is the same warm off-white used in the main feed, distinguishing LinkedIn's warmer professional tone from the cooler, crisper grays of Twitter or GitHub.
