This was a fashion fad that was apparently big in the 70s…I don’t know, I wasn’t there. However, I was there in the 90s when these things had a huge comeback! I can’t remember what all the colours meant; I think blue was happy, green was calm and red was love? I don’t know. What I do know is that the mood ring was responsible for the death of Macaulay Culkin in My Girl. So you better figure out what colour represents “sorry for murdering Vada’s best friend with a swarm of bees!” Can I suggest that colour being purple?
