Three colour variants are recognised in the United Kingdom: the dark, the original colour; the Jubilee; and the double-laced blue, which is rare. The Entente Européenne d'Aviculture et de Cuniculture and some European countries recognise the white variant in addition to these three. In the United States, the Cornish is recognised in four colours: the original dark, added to the "Standard of Perfection" in 1893; the white, added in 1898; the white-laced red, added in 1909; and the buff, added in 1938.
