Fungsi
This template generates the appropriate colour for a taxobox.
It should only be used by other taxobox templates.
Use by taxonomy templates
Manual taxoboxes call this template from {{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). {{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").
Setting colour within a taxobox
Both manual and automatic taxoboxes usually generate their colours automatically. If this fails, or if for some reason the automatically generated colour should be over-ridden, |color_as= can be used to set the colour based on a supplied taxon. Thus:
| color_as = Animalia
within a taxobox forces its colour to be the one appropriate for animal taxoboxes. The taxon given as the value of |color_as= must be in the switch statement in this template. Thus |color_as=Felis fails and assigns the error colour.
