Author's Note: How Color-changing Ice Cream Works

Researching this article rekindled my interest in color perception even more than the now infamous "is it blue or is it white?" dress on the Internet. It's a topic that everyone thinks they understand until they start researching it. But it also reawakened an interest in the rich history of pigments, a history dominated as much by happy accident as by careful chemistry, in which monopolies on particular colors could drive fortunes.
