Via Cheddar is usually a pale yellow (off-white) natural colour, but food colourings are sometimes used. In parts of the United States and Canada, annatto, extracted from the tropical achiote tree, is used to give some Cheddar cheeses a deep orange colour. The largest producer of these cheeses in the United States, Kraft, uses a combination of annatto and oleoresin paprika, an oil made from paprika.
