Thanks willus for the idea and example.
I was looking for the feature in Calibre for the following application benefits:
when converting epubs to PDFs in Calibre simply
customizing the background color and fonts color.
Would be great also to be able to convert Epubs to PDFs
with custom background color and font color in Batch.
It would be also of great help for dyslexic people,
or people with reading disability wanting to convert their Epubs to PDF with Calibre.
Would save time and steps. The customization is already
available in Adobe Reader since 2013 at least as shown here:

Here Kovid said (in 2016) it was difficult in Calibre:

Why since it is possible in Adobe Reader since 2013?
Thanks for any further help you can all provide.
Cheers
