Whenever you add colour to your documents, this should have a concrete function in helping the user of your publication to easily understand and interpret the data and explanations you are giving.

The use of colours without contribution to a better understanding is discouraged.

You will find further information in the Administrative Circular AC/24/2009 on the use of colour in IEC documents (published on 24.7.2009).
