Brown HT, also called Chocolate Brown HT, Food Brown 3, and C.I. 20285, is a brown synthetic coal tar diazo dye.

When used as a food dye, its E number is E155. It is used to substitute cocoa or caramel as a colorant. It is used mainly in chocolate cakes, but also in milk and cheeses, yoghurts, jams, fruit products, fish, and other products.^[1] It may provoke allergic reactions in asthmatics, people sensitive to aspirin, and other sensitive individuals, and may induce skin sensitivity.^{[citation needed]}

It is one of the food colorings that the Hyperactive Children's Support Group recommends be eliminated from the diet of children. It is banned in Austria, Belgium, Denmark, France, Germany, United States, Norway, Switzerland, and Sweden.^[2]

It is used in nearly every major brand of chocolate flavoured milk in Australia.^{[citation needed]}
