Ashley with the pink hair

Hello, my name is Ashley, and I go in high school in the us. I'm just a ordinary girl, but I have pink hair. My class and I just took the yearly group picture, and they photoshopped my hair color!? I feel really violated! It's my hair and I'm the one to decide which color it should be! My classmates and parents is really supportive, but its an different story with the school-board, they want me to change the color. But I won't, it would be like changing my personality.
