3.2.1. Make sure that information is comprehensible, even if the colours are absent

Information must not be conveyed solely by colour.

To test this point, you can first convert the mock-up to black and white and check that all the information is still comprehensible.


In the first example, the information in the pie chart can only be understood by associating each segment with a colour; the second version is comprehensible even if the colours are absent.

In this example, pictograms are used instead of squares of different colours.
