Since coolant and engine oils are both two separate insoluble entities, when they get mixed in the engine the formation of microbubbles starts taking place due to high engine revs. This causes the mixture which appears to be milky.

Engine coolant is a combination of some form of glycol and water. Glycol presents several problems when mixed with engine oil. First is, it does not boil away, like water. So it turns engine oil brown & milky.

It is milky because of the coolant and oil doesn't mix properly it may be water or other gas. If the coolant is leaked in an engine in these the reaction is exothermic.
Liberation of gas so colour is milky.
Liberation of gas so colour is milky.

They had not mentioned about which coolant it is. There are engines which cooled by water. Suppose this engine cooled by water, if this coolant leaked to the engine oil, the oil remain black.

Engine oil is nonpolar and violent is polar if both mix there it forms sludge particles which is in white colour and it also causes for engine Chemical wear.

Here not mentioned which type of coolant used. Mostly we use water as coolant then it become black because oil is black.

Practically when engine oil and coolant water comes into contact it changes. So therefore we say it turns milky.

Coolant oil colour is blue, then the engine oil color is black then the mixing the colour is white (or) milky.
