Just open heraldic books. There's been life nong before the Internet,
and color printing (with numeric technologies) is still a recent
technology and before that was always very expensive (and before that,
manual painting of books was only in exceptional documents kepts today
in museums or famous public libraries).
The hatching system has been used since centuries, and most prints
were only black on white up to the mid of 20th century (in western
countries) and is still predominating everywhere else where color
printing is too expensive).
And even today, we cannot always use true color on lots of medias,
that's why we still use conventional symbols or notations.
