Re: Babbage and Dark Mode

Babbage explored (in the paper & ink era!) many of the
issues raised in the Dark Mode thread. There is a book of
mathematical tables in the Science Museum in London, which
he had printed with varying type colours on varying paper
colours. His objective was to see what combination was
most reliably readable. I don't remember his conclusion,
and unfortunately I haven't been able to find an image
online.
