Perhaps, it's the colours that started the story

The colour she sees first is the colour of his eyes. Of the boy she singles out in the crowd, just barely eleven, she can tell, yet she doesn't know why she chose him, why when she sees him, she sees the colours. They were supposed to see the colours together. Instead, she was the one who saw first. Written for the Quidditch League Fanfiction Competion, Season 9; Round 12
