It is perfectly possible to do this in plain TeX with the assistance of
dvips specials. I have found it best to leave the basic mode alone, for
output as black and white text, and to introduce gsave . . . grestore
specials only where I need specific colors. Most of this is done for
multi-color covers for journals, and in one case I have to declare a
general color environment for the text type that covers several pages.
That is done with dvips's bophook (useful because it works without
pretencing that a special color environment can carry over a page
boundary). Any inserts in other colors are provided with gsave . . .
grestore inserts. Maybe this can be done in LaTeX, but the tendency to
hide simple actions in deeply nested macros-within-macros seems to me to
create problems where none need exist.
