Why is milk white?

Milk is white. It is because of a protein called Casein.

The cream found in milk contains white coloured fat.

Another reason is milk contains casein. The molecules of casein reflect all the colours of rainbow spectrum which has Violet , Indigo , Blue , Green , Yellow , Orange and Red. Because of this, our human eye thinks milk looks white.

If milk absorbs all these colours, then it would look black !
