I used to think Colgate's "Total" toothpaste would be different colours all in the one tube. An older ad for it showed them squeezing it out of the tube, and it was different colours each time. A few months later I stayed over at someone's house and they had the toothpaste. Much to my disappointment, it came out white, and only white, just like the boring toothpaste I had at home.
