I'm doing a little fiddling with new film developers. Been having some problems. So, what color is your phenidone? Mine is a little bit orange and I don't know the vintage. What color is your catechol? I have one that is pretty white, maybe a little purple or grey, just a cast. Another bottle is grey and stinks. I haven't used either in years and will replace as soon as possible, but don't want to replace with something that is the same. Anybody ever use Artcraft chemicals? Thanks.
