If you look at the colour palette again, you will notice that there are different shades of colour. Have you ever noticed this before? Some are light shades and some are dark.
The picture shows two images of a green ball. The first one is has a single shade of green and it looks flat – it doesn’t look like a ball. The second one looks much more realistic. Even though the picture has many shades of green it looks like a green ball.

Examine some pictures and photographs. How do different shades of colour indicate the shapes of objects?
How many shades of green are there in the picture of the nasturtium leaves? How many shades of yellow are there on the buttercup? Are the petals flat? How do you know?
