The periodic table as shown in the English wikipedia (enwiki) uses categories to mark the metallicity of the elements. Each category has its legend color. Both the label "category" and its associated color are editorial choices (chosen by enwiki editors).

The categorisation is based on science, WP:RS. The colors used are chosen wiki-local.
