Ian: is it your intent for the user to do it page-by-page if only some
author-specified choices are objectionable? If so, this seems to place
an unnecessary aggravation on that user.

OK, though I believe that "user to configure" should include ability to
provide the override to replace any author-specified or user-agent default, 
rather than page-by-page, as the checkpoint suggests to me.

Another nit: "domain" of system colors, from which a choice is made.
My training suggests that "domain" applies to the definition of available 
values for a function, and that "range" applies to result.
In color-space, "gamut" may be the word you seek.

To avoid the issue:
Note: Allow the user to select defaults from among the available system
colors, preferably chosen from among the "safe 216" choices that are 
generally available: (0 3 6 9 B E) for each of three Red-Green-Blue primaries.

Good.
