Notes on ergonomic colour adjustment
If you select colours for the monitor in your application programmes,
take note of the information below.

required contrast of 3:1 and are therefore not suitable for continuous text and data entry.
When using several colours for characters and background and giving the primary colours full
modulation, you can obtain very suitable colour combinations (see the following table):
