As a licensee, you may modify symbols for your personal purposes as you wish. Please keep in mind that symbols lose their symbol character through changes and changes can make it difficult to learn how to use them out of context.
In the case of symbols published on the Internet or in printed materials, the following changes are permitted: changing the background color, combining several unchanged symbols, scaling, rotating and mirroring symbols. However, the following are not permitted: distorted representations, distorting combinations of parts from several symbols (e.g. head and body from different symbols). Please note the terms of use regarding the publication of symbols.
