Target colour:
In this area, you can set the colour that should be searched for in each field of view.
Use the arrow to accept the colour currently detected as the target colour.
NOTE
We recommend that you calculate the target colour with a correct model piece. Entered
values may deviate from the model piece.
Max. deviation:
Set the maximum permissible colour deviation (in ΔE - distance between two colour
coordinates in the CIELab colour coordinate system) (max. 50) here. This change is displayed to you
in the CIELab colour coordinate system. The cover of the sphere represents the maximum deviation.
Only the current target colour is displayed as a coloured sphere, the other target colours are
displayed as abstract spheres.
CIELab colour coordinate system scale
NOTE
The scales of the CIELab colour coordinate system are divided into increments of 10 and
show up to 50.
Δ L = brightness (difference from target colour)
Δ a = red / green parts (difference from target colour)
Δ b = blue / yellow parts (difference from target colour)
