Microsoft's four-color logo unifies its diverse product ecosystem under a consistent, approachable, and energetic brand identity.
The four-color Microsoft logo — introduced in 2012 alongside Windows 8 — uses the four quadrants of the Windows flag icon to unify Microsoft's sprawling product portfolio. Each color corresponds to a different product area: red-orange for Office, green for Xbox, blue for Windows/Azure, and yellow for Bing/devices. The four-color approach signals both diversity and cohesion, similar to Google's strategy.
