Variant spellings are permitted for two parameters, and they affect how the information is presented - "color" or "colour". The examples below display as at right:
{{Infobox model| name = Jane Doe| hair_color = black| eye_color = brown}}{{Infobox model| name = Jane Doe| hair_colour = red| eye_colour = green}}
Note that if both spellings are present, |eye_color= and |hair_color= are ignored.
Microformat
The HTML markup produced by this template includes an hCard microformat, which makes the person's details parsable by computers, either acting automatically to catalogue articles across Wikipedia or via a browser tool operated by a reader, to (for example) add the subject to an address book or database. For more information about the use of microformats on Wikipedia, please see the microformat project.
Sub-templates
Date-of-birth ("bday") information will only be included in the microformat if {{birth date}}, or {{birth date and age}} are used in the infobox. (Do not use these if the date is before 1583). Be cautious about using these if the person is still living, per WP:DOB.
