The optimal position in colourspace can only be determined by following
strict protocols that integrate knowledge of the visual status of the user
and is checked objectively using a Rate of Reading Test.
Once that is established, then it is possible to match the overlay or
overlay combination with the monitor using the Hue an Luminance controls.
For asignificant number of users there will be a drift or 'flip' in the
colour over the next one or two months and a reassessment will be needed.
It is advisable for all coloursensitive vdu users to increase the
characterspacing of the text they are looking at.
