OK so this one is a bit grim so apologies in advance.
I went halves with one of my housemates on a two pack of toothbrushes when we moved into our new houseshare. I asked which one she wanted and she said "the mauve one". Okay cool, no problem.
A few months goes by, and I notice how my toothbrush, the kinda purpley pinky one, was obviously well used, and her toothbrush, the mauve, or green one, looked pretty much new.
I casually mentioned this to her today when something came up about buying toothpaste.. Needless to say we are now both relentlessly gargling mouthwash all day. I have absolutely no idea why I thought mauve meant green, or like.. pale green, which is what the toothbrush is, but here we are.
TL;DR Thought mauve meant green and shared the same toothbrush with a housemate for several months.
