Just mixed my third batch in 5 years of Formulary 130 paper developer (Ansco 130). The very first batch I ever made was a very light tea color - 1 liter kit 2016. Second batch was 8 liters and was a medium tea color in 2018 and it has darkened with age but still tea color. This last batch is 2 liters and it is almost the color of a cola.

What color should it be?
I have read that it functions normally even if diluted working solution is kept for a couple of months and turns dark. Just not sure it should start out that way.
