Notes on ergonomic colour adjustment
If you select colours for the display in your application programmes, take note of the information below.
The primary colours blue and red on a dark background 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 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; light background colours are only suitable for devices which are operated with a refresh rate of at least 75 Hz.
–Colour combination not suitable because colour locations are too close together, thin characters are not identifiable or rigorous focusing is demanded of the human eye.
