If a final comment is needed from the Quality side, we will need more information with regards to the shade. Does the customer consider the batch to be lighter, darker, more yellow, more or less red? We previously requested you to provide us the batch number for the Standard that was being used to compare against batch U120384X71. Were you able t get this information?
Meanwhile, our Quality Staff investigated. They determined the batch was within specifications. They indicate that batch U120384X71 vs std in powder is: Slightly less red and slightly more yellow
In addition, batch U120384X71 vs std in drawdown application is: Slightly darker, slightly more red and slightly more yellow on the white card. Slightly less lustrous and slightly more blue at the luster angle. Very slightly less red on the black card
We would not consider this lot outside of the specification and therefore would not have any corrective actions for this conforming production lot or the product in the future
