colour.difference.JND_CIE1976#
- colour.difference.JND_CIE1976 = 2.3#
Just Noticeable Difference (JND) according to CIE 1976 colour difference formula, i.e. Euclidean distance in CIE L*a*b* colourspace.
Notes
A standard observer sees the difference in colour as follows:
0 < \(\Delta E^*_{ab}\) < 1 : Observer does not notice the difference.
1 < \(\Delta E^*_{ab}\) < 2 : Only experienced observer can notice the difference.
2 < \(\Delta E^*_{ab}\) < 3:5 : Unexperienced observer also notices the difference.
3:5 < \(\Delta E^*_{ab}\) < 5 : Clear difference in colour is noticed.
5 < \(\Delta E^*_{ab}\) : Observer notices two different colours.
