i had an archery student a couple of years ago who dyed her in streaks almost like a rainbow..... red -purple -orange - and 2 different shades of blue... ... she loved it... her whole personality seemed to changed after she did it.... .... and i hate to say this because i have fought mental illness issues all my life - but she was definitely wacky..... she talked about doing it for days before she did it.... ...apparently it was very expensive and it only lasted a few weeks before some of the colors started to fade... ...after a while it looked like a mix of pale blue pink and yellow and then she got depressed about it .... and re-dyed her hair to try and match her natural hair color......... ...........she was a kook in many ways... . always breaking up with boyfriends and bringing enlarged pictures of their faces to use for an archery target...... kinda spooky coz she became a very good archer....
