Notes on ergonomic colour adju
stment
If you select colours for the monitor in your application programmes,
take note of the inform ation below.
The primary colours blue and red on a dark backg round do not produce the minimum
required contrast of 3:1 and are therefore not suitable for continuous text and data entry.
When using several colours for chara cters and background a nd 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 o r rigorous focusing is demanded of the human eye.
