1. General
1.2. Use of colours
The use of colours is generally sparing.
What is meant by this?
A restrained and appropriate use of colours to convey information should be aimed for. Before the integration of colours into an information medium, it is advisable to carefully consider whether and to what extent they can contribute to improving the communication of information.
Why is it important?
For some recipients, too much colour can be a distraction or disrupt the reading flow due to strong visual perception. In addition, there are recipients who cannot perceive all colours clearly or who work independently of colour. If information is conveyed exclusively through colour, these recipients may miss important information or not understand it.
How can I implement/check it?
It is recommended that the number of colours used is kept to a minimum in order to convey a clear and understandable message. In addition, when deciding on the use of colours, consideration should also be given to their necessity to ensure that they actually add value to the communication of information.
If colours are nevertheless used to convey information, this information should also be conveyed in other ways, such as symbols, lettering or patterns (see 1.3).
