This isn't really new info though, people have known about this and been theorizing the thought months before this show even premiered, and what gave that theory away was yes, the gem colours do match the colours each girl was wearing. And I don't know if you know this, but during the first episode, Anne's eyes briefly glowed blue for a moment, which now people are currently theorizing about Anne not only representing the blue gem, but that some form of power from the music box absorbed itself into her.
