Question

Why colour of milk is white ?

Answer 1

Milk consists of about 87% water and 13% solids, such as fat and various proteins. The most important of these proteins is casein, one of the 4 proteins that make up about 80% of the proteins in milk. Casein ...
it is distributed uniformly and spherically throughout the milk and the reason is because casein molecules have a negative electric charge, causing them to repel.

White objects in nature appear when the light is reflected on the object. Usually there are colors that do not exist in the visible spectrum and are therefore reflected and give the impression that we are seeing white. So, as you have guessed, casein and some of the milk fats divert the light evenly, making it look white in our eyes. Without the fats and casein, the milk would look blue or even red. When the fat is not uniformly distributed, the milk gets a small dose of the blue color.

Milk also contains riboflavin, which can give the milk a slightly green complexion if its concentration is large enough.

Another hue that you can occasionally see in milk is the yellow color. This is due to small amounts of carotene found in milk.
