Notes on ergonomic colour adju
stment
If you select colours for the monitor in your application p rogrammes,
take note of the inform ation below.
The primary colours blue and red on a dark background do not produce the minimum
required contrast of 3:1 an d are therefore not suitable for con tinuous 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):

+ Colour combination very suitable
- Colour combination not suitable because colour hues are too close together, thin characters
are not identifiable or rigorous focusing is d emanded of the human eye.
