Rhodoxanthin is a xanthophyll pigment with a purple color that is found in small quantities in a variety of plants including Taxus baccata and Lonicera morrowii. It is also found in the feathers of some birds.^[1] As a food additive it is used under the E number E161f as a food coloring. It is not approved for use in the EU^[2] or US; however, it is approved in Australia and New Zealand^[3] (where it is listed under its INS number 161f).
