In this engaging title, young readers learn how visible light is the key to colour! Discover how light begins with the sun and travels to Earth on electromagnetic waves, how white light actually holds the whole colour spectrum, and how the eye perceives colour. These properties are illustrated by the mixing of paints and pixels. Colourful infographics make the electromagnetic spectrum, wavelength, and eye anatomy easily accessible, and prominent contributors such as Sir Isaac Newton and Russell Kirsch are featured. A fun experiment with light and water brings the science of colour to life!
