Notes
This page prints correctly in black and white, which is the practical payoff of the constraint: nothing here depends on a hue surviving a photocopier. If you add a chart, keep it to the same rule — encode the value in position, in hatch density and in a printed figure, and it will still be readable when the colour is gone.
