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.
Happy colouring!
