How artists paint light: from candle to sunrise

Five paintings, five ways of showing light, and what each one tells you.

Paint cannot glow. The brightest white on a palette is dimmer than most things we see in daylight. Artists have therefore had to find ways to suggest light using only contrast, colour and placement. Five works on this site show five different answers.

Caravaggio: light as a spotlight

In The Crucifixion of Saint Andrew, Caravaggio puts most of the scene in darkness and lets light fall on a few faces and on the saint's body. This strong contrast is called chiaroscuro, from the Italian for light and dark. The Cleveland Museum says the contrast suggests the presence of God. The effect also pulls the viewer in close, as if they were in the same dark room.

Vermeer: light from a window

Vermeer's Young Woman with a Water Pitcher shows soft daylight from a window on the left. There is no strong shadow. The light shows up in small details, such as the reflection of the blue cloth in the side of the pitcher. The painter can show how light passes through the room and picks up the colour of the things around it.

Turner: light as fire and air

In The Burning of the Houses of Lords and Commons, light is the fire itself. Turner uses bright oranges and yellows against the dark water and sky, and loosens the detail until the picture is almost abstract. The light becomes the subject, and the buildings and boats matter less than the glow.

Monet: light changes the colour

Monet painted the same haystacks many times to show how light changed their colour through the day and the seasons. In Stacks of Wheat (End of Summer), the shadows are coloured, not grey. This was one of the key ideas of the Impressionists: the colour of an object is not fixed, since it depends on the light.

Hokusai: flat colour and clear sky

A Japanese woodblock print cannot blend colour the way oil can, so light is shown by flat areas of colour. In South Wind, Clear Sky the red of the mountain suggests a particular time of year and day. The few white clouds against the blue make the sky feel wide. It is a reminder that a painter does not need realistic shading to give a sense of light.

A simple exercise

Pick one painting from the site and ask three questions. Where does the light come from? What is the brightest spot in the picture? What colour is the shadow? Answering them takes a minute and changes what you see. Then do the same with a second picture and compare. You will start to notice that every painter makes different choices about light.
