LibreOffice color palette

LibreOffice comes with an unattractive standard color palette that hasn't changed since StarOffice.
We gave it an overhaul and included MS Office standard colors (Larissa) in the process.
Documents can now include a uniform color palette and retain color layouts on different platforms.

Store this file with Save Link As... (right mouse click) under your .config/libreoffice/4/user/config folder.

LibreOffice color palette (incl. Larissa) or download it from GitHub
