When it comes to colour, most of us are on safe ground with the primaries – but when asked to differentiate between the different shades of blue, for example, we might start to struggle. That doesn't mean we're colour blind, more “hue illiterate”, perhaps – a situation not helped by the increasingly creative means paint companies employ to describe their wares – anyone for Farrow and Ball's Borrowed Light? Or maybe their Dead Salmon?
Very Hungry Caterpillar Mobile. Hang 8" lanterns (1 red, 6 in two shades of green) with different lengths of fishing line. Use pipe cleaners for antennae, and construction paper for eyes and nose. Makes me wish I taught primary again :)
