How come the bubbles/suds are always white no matter what color the shampoo is?

';White'; is actually just the colour you get from a mixture of all wavelengths of light. The bubbles are just reflecting back and scattering all the wavelengths of light hitting them, so if they're in sunshine or under a normal bulb, they look white.How come the bubbles/suds are always white no matter what color the shampoo is?
The bubbles are shiny for me =)
