So tell me, what color would you expect from fresh chemistry? Like I said, the 13.5 liter stuff mixed up to light golden color.
I've just checked the JOBO/ Tetenal C-41 5 Liter Kit I have - JOBO Part #109310 (? - from memory) and I can't find anything resembling an "Expiration Date". You have one on yours? Where did you buy the kit?

If perfect, I think the Color Developer concentrate would be "straw" colored -- there is a LOT of leeway here, apparently ... In the last kit I opened the concentrate was brown - definitely brown. Mixed, it is faintly light, light brown - and worked very well.

Lately, I've been using the 1 Liter C-41 "Press Pak" - dry chemicals - for the shelf life. I've been able to "cheat" successfully, using 250ml of chemistry in a JOBO 1500 Series tank to process two (2) rolls of 120, - therefore 8 rolls/ liter - instead of the 270 ml stated by JOBO. This stuff works well. I wish I could get dry RA-4 chemistry.
