The triumph of form over function?

In a different life I was discussing presentations to Cabinet with someone who had had to prepare one. He was instructed (he said) to present the final draft of the graphics (very multicoloured) to someone known to be colour blind; apparentlyabout a third of cabinet members at that time were colourblind. He did so, and received valuable advice that he's used ever since.
