Microsoft uses a four-colored window made of red, green, blue and yellow squares in its logo. The symbol accompanies the company name in Microsoft’s modern identity.
The four squares form a window-like shape, connecting the corporate logo with Microsoft’s Windows software brand. Microsoft introduced the logo in 2012 as part of a broader visual identity refresh. The wordmark uses a light, sans-serif style alongside the colored emblem.
Microsoft had used several earlier logos, including the “Pac-Man” wordmark from 1987. The 2012 design returned to a simpler geometric symbol and made the Windows connection explicit without using a detailed illustration.
The colors are often listed as red, green, blue and yellow, but the logo is not the Google mark, which uses a multicolored letter G. The four panes are also not intended to depict four separate products in a fixed official list.
