Small note of interest. Using a //e and an Extended 80column AppleColor card
in combination with the AppleColor RGB monitor would allow software control
over foreground and background colors per character. I don't remember all of
the details but I do remember that the color information was stored in Text
1X of aux memory. The high nibble controlled foreground color and the low
controlled background color. If someone has such a setup, I'd like to see if
it was just a peculiarity of my old Apple //e or if it really was a feature
of that card and monitor.

Several RGB cards for the Apple II could do that. They simply replaced

There was normally no software control but you could use switches on
the
card to select the colours e.g. cyan text on a dark blue background was
a favourite.
Now that brings a question to mind... is it possible to change the text
colour by changing a ROM or something? I suppose it would only work with
non-Apple monitors, though...
No.
Text mode is a monochrome (no burst) mode, and the RGB
cards that do the trick sense this and remap "black" and
"white" to user-chosen colors on an RGB monitor.
There is no corresponding trick on a composite monitor
that would work for text (lots of isolated pixels).
