{{Sets taxobox colour}} is a utility template used by {{Taxobox}}. It checks whether its argument, which should be a taxon name, has a taxobox colour defined in {{Taxobox colour}} but is not "incertae sedis". If this condition is true, it returns the taxon name, otherwise it returns blank.

The template assumes that colours defined in {{Taxobox colour}} use the format rgb(..,..,..).

The template should only be used from within other taxobox templates.

{{Sets taxobox colour|taxon_name}}

It returns the taxon name if the condition is met, otherwise blank.

• {{Sets taxobox colour|Animalia}} → Animalia,

A taxobox colour is explicitly defined for Animalia.

• {{Sets taxobox colour|plantae}} → plantae,

The taxon name can have an initial capital or not.

• {{Sets taxobox colour|Acacia}} →

Although Acacia is a plant genus, the taxobox colour is not explicitly defined in {{Taxobox colour}}; in an actual taxobox it is set by finding that Acacia is a member of Plantae.

• {{Sets taxobox colour|incertae sedis}} →

Although "incertae sedis" has a taxobox colour defined in {{Taxobox colour}}, it is ignored. (This is so that templates that use this one can continue to look higher up the taxonomic hierarchy to see if there is a more appropriate colour; an incertae sedis family, for example, may be known to be an animal, when the Animalia colour should be used.)
