What colour is Yak's milk?

Pink, because of the blood content it has.

SR, the only reference I have ever found for this is a trivia site. Do you have a better one?

'a rich creamy color'
Here is a site run by a company that raises yaks. In their FAQ section, they dispell the myth that yak's milk is pink.

No, Dorian, you are quite correct. I went back and it appears that each of the sites I referenced were trivia oriented. I could not find any scientific confirmation.

Nice work, Methos.

Thanks, Methos. However, I advise anyone playing in a Trivia contest, if asked the color of yak's milk, to ask the judges if their source was a Trivia book or site, or one from a yak breeder.
My experience at these contests tell me that this one will be hard to dispell.

Good going, Methos!
