We also have same chart with you because we cut leather in to half and send those approved to you, so there is no need to provide us the new family chart. We still have the same chart for discussion. BTW, we also checked colour of this lot with previous approved sample that has same colour with shade #1. But for this lot, it is darker than shade 1. I am not sure that you still have previous approved sample in your hand or not, but it would better to use that sample to check with current process as well. If you would like to get previous sample back to you for review please let me know.
As I ever told your team that we accept the range that in between acceptance level of light and dark, I would suggest you to match the colour in the middle range. If it is shift from the middle range, you still get some variation within the range. Matching with the darkest or the lightest is risk for colour variation shift to out of spec. BTW, please check your mixing tool. I am not sure that it has effect to this problem or not.
