The colour of an object.
How to record
Use a single term, without punctuation or capitalisation unless this forms part of the name of a colour. Maintain a list of standard terms. Record colours which are important for retrieval purposes. If an object comprises many colours, record that fact only if it is significant in the production of the object. Record colours in the Physical description in the context of other aspects of an object.
red; blue; polychrome
As many times as required for an object.
