Abstract
Mathematical diagramming serves many purposes in mathematics research and education. It may be
conceptual or representational in form, but in all cases, producing graphic presentations benefits from
carefully considered use of the various elements of graphical composition. The challenge of mathematical
diagramming – indeed, of all diagramming – is how to do it well, so that the diagram fulfills its specific
conceptual and communicative purposes. This paper and workshop will examine how the considered use of
colour in diagramming and in corresponding artefacts can identify and clarify mathematically pertinent
features with respect to various mathematical insights. The idea and role of aesthetics in diagramming will be
considered with respect to various representations and artefacts of interlacing and some of the related
sensitivities, especially colour sensitivity, will be exercised. The reader should note that since the proceedings
are printed in black and white, it is worth consulting the electronic version in the Bridges Archive1 to see the
colour images.
