The authors of this article (a chemical engineer, a designer, a visual artist, and an architect/designer) present their proposal for the main topics of a colour science course aimed at nonscientists. With examples taken from their own respective teaching practice, they describe and discuss the main topics they consider important to be included in the curriculum of future visual artists, designers, and architects. They also sample over a dozen text books written for this public audience and point out some of the most striking examples of misconceptions to be found in these.
