title: Colours for sizes: a recommended ergonomic colour code.
abstract: An ergonomic colour code for sizes should use colours the way people think they should be used for sizes. The results of a simple investigation suggest that red should represent the largest size, and probably white the smallest size. The intermediate sizes could be represented by colours arranged in rainbow order.
