Hi Christoph. First of all a great job on the figures

Speaking about color and clothing in that period

If you could get this book from your library Natural Dyes by Judy Hardman its a book how to use natural Dyes from your Garden and how to use them on wool, cotton, slik and I think flax

. I checked it out my self and learned a lot.

I have talked about this before about color in this form

Remember most of the time you are dealing with pre industrial Dyes and methods used. Also another book

is The Chronicle of Western Costume . I use this a lot when painting
