First color example.

I thought the enthusiasts here might want to hear! I'm excited.

It is drying in the darkroom right now . Scanning tomorrow.

I used Red 1 Azo dye in an AgCl coating and gave it a "normal" dye bleach process after a "normal" B&W process.

The Bleach was H2SO4 (~4%), Phenazine (~100 mg/l), NH4Br (~20 g/l), and Thiourea (~20 g/l).

I followed this by a wash and a blix and then a wash. I got a quite distinct positive magenta / red image. A lot of dye washed out even though I used an Aluminum mordant, and the coating blistered indicating poor hardening for this process.

But, it is my first color coating, not my last.

I have Metanil Yellow for the yellow layer, so if I can get a Cyan dye and a good red sensitizer for this emulsion....... Maybe. IDK. The only Cyan dye I can easily get is Chicago Blue, which is not the best "cyan" in the books but bleaches well.

You know what? This is just way, way too cool. Sincere congratulations. I can't wait to see the scans. The individuals on this site and what they know - and what they can do with that knowledge - never ceases to amaze me.

That is great! Now if you can just keep the troll from asking about scavengers ... jest sayin'

You know that you are trolling right there, don't you?

Actually, if I ever get to a multilayer, I will need a scavenger.

Yes, you. The one who keeps splitting hairs about a discussion long after the discussion is done. [Do you need an mirror to see who it is?] But you are providing a service of raising my post count, even though it is not on my agenda.

Would a competer not do?
