like when using soap/shampoo etc why are the bubbles always white no matter what colour the product is?

Actually, the foam in its entirety looks white because when light enters the soap solution, it must pass through a number of tiny soap bubbles, i.e., a number of surfaces. These countless surfaces scatter the light in different directions, which makes the foam/lather always look white.
It is because natural light is white.
The bubbles are just reflecting natural, white light.
If oyu go into a dark room for photography, or turn on a black light, then you would see red and purple bubbles/foam.
They aren’t always white. I make soap and the color of a bar affects the lather. Currently Ive got an orange bar in the shower that lathers orange.
If you’ve ever watched candy making videos where they stretch it over a hook, it’s the same principle.
Other comments describe it better, but I thought this was also interesting to watch to see how it slowly changes as they put more air into candy.
