Notes on ergonomic colour adjustment
If you select colours for the projector in your application programmes, take note of the information
below.
The basic colour red and blue on a dark background do not achieve the minimum contrast of 3:1
and should not be used.
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 locations are too close together, thin
characters are not identifiable or rigorous focusing is demanded of the human eye.
