The Colour Badge

Duggee is painting in his favourite colouring book. The Squirrels want to have a go too. Betty wants to paint a bee and that's yellow. Tag paints a fire truck and that's red, and Happy paints some water blue. But when it's Norrie's turn she can't find the paint colour she wants. Don't worry, Duggee has his colour badge, he can mix colours together to make different colours. What other colours can you make, Duggee?
