Question

How come no matter what color the liquid is the froth is always white?

Answer 1

yes baby due to oxygen molecules present in water

             simple but sometimes colour do appear something like dark blue.

Answer 2

While that is not entirely true, it appears to be white(r) because of the oxygenation of the liquid.

Primarily due to the diluting of the substance, froth lightens in color with more induced agitation and the surface of the substabce along with the resultant bubbles reflect a lighter or "whiter" color.

Answer 3

air is mixed in with it. molecules.

Answer 4

Air bubbles have only a thin skin, so appear transparent.  Enough together and the reflected light makes them appear white.

Answer 5

It's not.

Answer 6

I don't think they're pure white; more like a very light hue of what the actual drink is.

I've had some full-bodied beer, the kind that's really dark, and their foam/froth is a bit tan colored.

Good question!!
