Is She A He?

I’m beginning to think my pet parakeet Amigo is well…… a HE!!!!!! When I first got Amigo at the pet store, the lady that sold me Amigo said that you can tell if it is a boy or a girl by the color of the band that is above its beak.  If it is pink, it’s a girl, if it’s any other color, it’s a boy.  And at first it was pink but now it’s not…………….if anyone has a 1 year old parakeet, tell me if this is normal.
