How come when you put pink, purple, or even green bubble bath or creme into your bath the foam is always white?

I'd love to have a multicoloured bath.How come when you put pink, purple, or even green bubble bath or creme into your bath the foam is always white?
There isn't enough pigment to sustain the color when it's expanded. When you put it into the bath, it's going to break apart and get stretched into all of those bubbles. Crayola has some colored bath products like colored bath fizzies. How come when you put pink, purple, or even green bubble bath or creme into your bath the foam is always white?
