The color disaster

This is an original story that I've always wanted to share!

For this story there are very little people in a make believe world and all of them with be born with a certain color hair from the rainbow such as red, orange, yellow, green, blue, pink, and purple. You live a perfectly normal life but you have to dress in your color if you break that rule you'll disappear forever and never come back. But there's a twist it's only one boy and one girl per color the girl/boy that has the same color as you has to be the same age and will be your soulmate but something happens with a couple characters that should make them disappear but don't.
