This list of more than four hundred links to free resources on colour began more than ten years ago as a rarely visited page on my teaching website that I started using to record interesting links as I came across them, mainly for my own benefit. I've periodically done some work organizing the list and filling in some gaps, but the coverage is still patchy, even within my own areas of special interest. If you know of any good additional links reflecting a modern understanding of colour and of interest to artists and designers please let me know! (No red-yellow-blue, primary-secondary-tertiary "colour theory" except for the historical section, thank you!). I will be using the list as part of my contribution to the Colour Literacy Project, an international educational initiative jointly undertaken by the Inter-Society Color Council and the International Colour Association to provide age-appropriate colour curricula and state-of-the-art resources for teachers across science, art and industry.
