Mixing Colours

Max has a puzzle for the Tweenies: how do you make six colours from only three pots of paint? They struggle at first, but by accident they discover that by mixing two colours together they can create a new colour. Proudly they present Max with six pieces of paper, each painted a different colour. Max is able to stick each piece of paper on the sides of a cardboard box to make a giant coloured die, which they use for a colour game.
