E. J. Wall wrote filter making instructions in his 1922 book, Practical Color Photography. The book is not difficult to locate but you can also download it for free at this link: https://archive.org/details/practicalcolorph00walliala

Chapter 2 describes how to make separation filters. Chapter 11 gives complete directions for making a photochromoscope, and the viewing filters. Wall describes the issues surrounding the selection of appropriate taking and viewing color dyes.

I think you might find what you are looking for in this book.
