Query: Did not change color of hair

I just colored my light brown hair with this...carefully made sure it was evenly distributed, etc. I waited 25 minutes (probably a little longer) and washed it out, eagerly anticipating a head of coppery hair like on the box. Was I disappointed. You can't even tell that I colored my hair. It seems to have lightened it a half shade, other than that, NO RED/ORANGE color AT ALL. So angry. What a waste of time and money.
