Mustafa, I actually see two questions intermingled in your thread:
- What were the cut-off points of the filters used to create the two images on the two parallel running films?
- What was the exact dye composition of the dyes used in this two color process?
I am slightly afraid there will not be a hard answer to these, as you yourself already wrote:
Of course, some record of used equipment and dyes might help to get in the ballpark for replicating the process and colors, but in the end, I think you will just have to give it a try and see what works best. Maybe you could consider contacting George Eastman House, as the original video I posted here on APUG and that spurred your interest in all this, came from there. They may have some records on this.
