In the following, we set up an automatic coloring method in order to address these problems. Indeed, we describe a simple method that automatically generates an intuitive color code showing proximity relationships between data in any hierarchical classification. The presented algorithm, named ColorPhylo, associates a specific color to each item so that the taxonomic relationships are shown by color proximity (the closer two items in the tree, the more similar their colors). Colors can thereafter be used in any user's analyses and figures so as to display taxonomy.
