Students were given paint palettes with three colours of paint – red, blue, and yellow. The instructions were to paint any picture they wanted but they needed to show six colours – both primary and secondary colours. To be fair, they mostly made ‘intermediate’ colours as the colours they created were most likely not of equal amounts of primary colours. Most students managed to make secondary colours (orange, green, and violet).  Some people discovered what happens when they mix too many colours –  they get brown.
