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):
Background Characters
black white purple blue cyan green yellow red
black + + - + + + -
white + + + - - - +
purple + + - - - - -
blue - + - + - + -
cyan + - - + - - -
green + - - + - - -
yellow + - + + - - +
red - + - - - - +
+ Colour combination very suitable
- 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.
