Colour in publications

For most documents produced by the IEC, the use of black and white is sufficient. Colours in figures, tables or text shall only be used where they facilitate the use of the document. They have to serve a purpose in helping the user to easily understand and interpret the data and explanations given.


The use of colour for purely aesthetic purposes is not permitted.

Please follow our grey scale and colour recommendations to ensure maximum readability.

 

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