When you add liquids to the cabbage juice, very acidic solutions will turn it a red color; neutral liquids make a purplish color; and basic solutions will make cabbage juice a greenish-yellow.
Well, It will turn into a kinda violet purplish color. Because, When the milk turn into a red cabbage it absorb to a mixer and that's how the acid become a acid base I guess..... So, It will be a lighter or darker purplish color.
