The amount of dye in them isn't usually enough to make the foam that colour. Now, if you get a shampoo that's made for keeping yellow out of grey/white hair (which is usually deep purple or blue), the foam will be that colour. The same goes for these new shampoos for brunette and red hair- the dye in them is enough to make them foam that colour.

Some companies (like Dove) use colors to distinguish one shampoo/conditioner from another, but since there's the same base chemicals the foam is always white, the dye doesn't make a difference.
Something like that.

Ok, I'm not certain about this, but here is my guess.
The lather IS different colors, but the tiny amount of actual soap in each bubble is not enough to display any depth of color, so it really just reflects the room light. It just scatters the light.
Sounds reasonable.

I had a blue shampooo and the bubbles were blue, so its not an always thing.
