Background Pony #7AFD
A tag can be assigned a category, which changes their background color, and all tags of a particular category are grouped together in the tags section of an image.
For the most part, they just enhance the clarity with which tags are presented to users, and rarely are something users have to interact with - except to point out new characters, new species, and new fan-creations to get them added to those respective categories.
Tag categories are only loosely and indirectly documented. Their existence, and that you can use it as a parameter for searching for tags, is noted at the bottom of the tag list/tag search page. The current list of categories in use is listed on the API documentation page, of all places… Likewise, you can find what category (if any) a particular tag is assigned via the two API endpoints that return tag-response or by inspecting the page source and looking for the
data-tag-categoryattribute of the span representing each tag displayed on the page.
There’s at least 1 category not listed on the API page: body-type (eg. “anthro”)
