Dear all,
these indicators are good tools to warn you if you are in non D50 light.
They are not suitable to determine if you have a good D50 simulator.
If you do not see or only barely visible differences it _could_ be that you have a good D50 simulation.
If you see big differences between the metameric pairs you definitely do not have a suitable D50 simulation.
The second application is what these strips are meant for, the first not.
Best regards
Claas
