Orange B (red shade) – allowed only for use in hot dog and sausage casings (not produced after 1978, but not delisted) Many dyes have been delisted for a variety of reasons, ranging from poor coloring properties to regulatory restrictions. [42] Some of these delisted food colorants are: FD&C Red No. 2 – Amaranth, E123
In 2008, the Food Standards Agency of the UK called for food manufacturers to voluntarily stop using six food additive colours, tartrazine, allura red, ponceau 4R, quinoline yellow WS, sunset yellow and carmoisine (dubbed the "Southampton 6") by 2009, [14] and provided a document to assist in replacing the colors with other colors.

A Tsáchila man, with his hair coloured with annatto. The annatto tree B. orellana is believed to originate in tropical regions from Mexico to Brazil.
