Editing Template:Taxobox colour/doc (section)

=== Use by taxonomy templates ===
Manual taxoboxes call this template from {{tl|Taxobox}}, which looks at the values of ranks given in the taxobox from phylum upwards and uses the taxobox colour for the first colour-setting taxon found (or the error colour if none is found). {{tl|Sets taxobox colour}} is used to decide whether a taxon is colour-setting, which it does by using this template.

Automated taxoboxes use a function in [[Module:Autotaxobox]], which finds a colour-setting taxon by searching up the taxonomic hierarchy coded in taxonomy templates (i.e. templates with names of the form "Taxonomy/''taxon-name''").
