Are you wondering why we picked the name Newton's Rainbow for our first colouring book? It is a tip of our superhero hat to the fundamental science underpinning colours and light.
In 1665, Isaac Newton passed light through a prism and watched it fan out into a rainbow. He thought he could see seven colours—red, orange, yellow, green, blue, indigo, and purple. These are just some of the colours we hope you use to enjoy our unique colouring book.
