I love to get children experiencing how different colours can be produced just by mixing three primary colours.
It is easy for them to make orange, green, or purple. But there are many other colours. For example, there can be ten different levels of orange, some are lighter, some are stronger. Therefore, I asked everyone of them to observe, letting them think about questions like, “what is the colour of grass under the sun? What is the colour of grass in the shade? ” and ask them try to mix these different greens by mixing different amount of yellow and blue, even try to put a bit more red inside.
When the girls get one more paint, the colour mixing became even more magical. They have produced their own colour palette. More important, they can create their favourite colours not once, but several times. This means they have established the logic of colour mixing.
