There might be a misunderstanding. Perhaps you saw a picture or video where the milk appeared pink, but this could be due to:
* Lighting: The way the light is reflecting on the milk can make it appear a different color.
* Mixing: If the milk is mixed with other ingredients, like fruit or food coloring, it could turn pink.
* Processing: Some processed yak milk products, like yogurt or cheese, might have a slightly pink hue due to the fermentation process or added ingredients.
Let me know if you have any other questions about yak milk!
