Last week I went to Wuhan (China) where I was invited by the Department of Industrial Design at Huazhong University of Science and Technology to give a two-day workshop on colour and a lecture. In the workshop I asked the students to arrange a set of colour chips in a logical order. Here is the result.

The last four images show the final work by each of four groups. Group 3 were the best in my opinion. Of course, this task is difficult, if not impossible, in 2-d. Colour perception is at least 3-d and the dimensions are lightness, chroma and hue. The workshop task was designed to enable the groups to explore the ontology of colour perception. It was also good fun!!!
