That's a moot point! If one uses colour for transient purposes
(e.g. to highlight a few words, or a single paragraph) then one
would prefer that a .LP would restore the default. On the other
hand, if one uses colour for extended passages, then it is more
convenient to have the colour carry through.

Likewise, regarding font- and size-switches, one can set global
changes in ms macros by

.fam BM \"for Bookman
.ps 15
.nr PS 15 \"to change the default font to 15 points

However, I would agree that for consistency of logic in ms macros,
changes in colour would be local to the paragraph and revert to
the default at a new paragrpah; and there would be a register
(analogous to \n[PS]) to make a global change.

That being said, I personally prefer to cancel colour explcitly
when I have done with it, whether that is after a few words,
at the end of a paragraph, or after an extended passage.

One one is used to it, it is very little trouble to do.

Best wishes,
Ted.
