I can think of a couple of options, but having problems
remembering any details.
Your "purple" solution could involve either an Iodine
reducer of Potassium Permanganate reducer.
There is a process I have tried some 5-7 years ago called
"Bleach-Etch" process. Here a print is immersed in a bleach/etch solution,
(no details to hand on this solution, may have information elsewhere if needed),
then swabbed with a cotton wool pad to remove loosened gelatine. Reollect
that after this I dyed the remaining gelatin base with a food dye or
similar.
Possible reference, Kent E Wade, Alternative Photographic
Processes published by Morgan & Morgan, 1978. There is a chapter
on Beyond the Black & White.
If you want any further information please get back to me
privately. jimth@xxxxxxxxxxxxxxx May
have more time next week to look for old notes.
