A Different Kind Of Rainbow

In a world filled with colour Elina Ariel is grey, literally. She lives in a world where everyone is assigned a colour when they turn 13, but Elina, she got nothing. Your colour defines your future, as far as anyone was concerned Elina didn't have a future.Maybe it was a mistake in the program but the impact was HUGE. She was looked down by everyone that saw her, all her friends disappeared after lack of a colour. Barley anyone acknowledged her.
But, that was before Harry Sullivan came. He was the exact same as Elina while being the complete opposite...
