The text that gets replaced can be a different color than its block parent with the text-overflow:ellipsis, but it still uses the parent color, not the text color. Try this in the snippet editor, and then resize the window:

Confirmed in Safari and Opera and updated accordingly.

Thanks very much for the test-case and correction Brad and confirmation Robert.

I appreciate the feedback.

We're not quite at the point where editorial polishing is worth it -
as text is likely to change more for functional reasons (e.g. in this
case, the quoted text has already been removed for functional
reasons).

Please await a public LCWD for editorial comments. Thanks!

If that's so, then web authors/developers are unlikely to be depending
on things other than "the simplest situations".

That will do for CSS3-UI.  Anything that is currently not
interoperable among the three implementations I will leave explicitly
undefined / up to the implementation in CSS3-UI.

If any particular implementation thinks they have the best answer for
any of these details, I'm willing to write-up such details in CSS4-UI
assuming other implementations agree and are ok with changing their
implementations accordingly.

I encourage test cases illustrating such non-interoperable behavior
*now* however, in the interest of providing implementations the
opportunity to proactively change to interoperate on such details,
which I will then be more than happy to add to CSS3-UI.

Already did as cited in my original message of this URL:
http://www.w3.org/blog/CSS/2009/11/25/resolutions_84

If there are specific cases from those lists that you're worried about
please list them specifically, preferably with an illustrative test
case. Otherwise I leave the implementation of such details up to
specific implementations, per their judgment (what's best for web
developers / performance etc.)
