    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.
