>>You'll see a color change when you mix the stock solutions and the water- that's good PMK.(posted 8890 days ago)CRUCIAL!!!
Once you notice what the colour SHOULD be once you put A and B into the water, if you ever notice the colour is DIFFERENT, then something is WRONG. Don't ruin your film by discounting dis-colouration. PMK is extremely sensitive to chemicals/contamination; and I have noticed dis-colouration is a prime indicator of contamination.
Believe your eyes. Dump the stuff. Clean everything, and start again.

ps I've noticed with different emulsions the colour change AFTER development varies, even with the same emulsion. Don't let this worry you; it's normal in my own experience. (i.e., when you go to the afterbath stage).
