92 Chapter 4. Colour Management in the Graphic Technologies
We need to give these memory colours a priority when we evaluate our colour management efforts. If
these key colours aren’t right, then everything will look wrong.

The significant impact of our mind’s contribution to colour perception enforces the requirement to
take colour matching beyond the raw numbers we can extract from the physics and physiology of
light’s interaction with an object and our optic systems. The psychological components such as colour
constancy and memory colours can only be accommodated by human intervention in a colour
management system.
