If you select colours for the monitor in y our application programmes,
take note of the information below.

required con trast 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):
