There are 196 countries on earth and none of them use purple on their national flag! What's wrong with purple? It's such a popular color today. Why would no country want it on their flag? Sometimes the simplest questions have the most extraordinary answers! This is the incredible true story of purple! Take a journey back to a time when purple dye was worth more than gold, diamonds or castles. This book was inspired by our original animation that has gone viral across the world. We decided to expand the story and enhance the art. Our mission is to make learning fun and to teach ideas that you won't necessarily find in a classroom.
