Sugar is the Linux-based operating system developed at One Laptop per Child and installed on the XO laptop. Sugar Labs is a non-profit foundation that serves as a gathering place for the community of educators and software developers extending the Sugar platform and developing Sugar activities. The logo utilizes a fundamental visual treatment of the interface—the use of separate stroke and fill colors to identify people. The typography is treated in the same way that symbols are treated in Sugar. Alternating between 12 color combinations, the logo represents the diversity of the open-source Sugar community.
