Varying brightness levels won't generally be a problem for color-blind
users, although people do tend to have less sensitivity to contrast as
they get older.  I was mostly reacting to the idea of switching an icon
between red and green.  Not only would that be a use of color indicators
when other means are available, but it's quite possibly the worst two
colors that could be suggested.

In general, I think having an icon "fade in" while the file is written
would be slick from an eye-candy perspective, but I question its actual
usefulness.  If I don't have the fully-rendered copy right next to it,
how do I know what the finished state looks like?

Super-imposing a progress bar on the file would be much more useful.
When I look at a progress bar, I can immediately tell how far along it
is, to a certain degree of accuracy.  A fade-in effect on top of that
could look really nice, as long as it didn't get in the way.  (Please
don't start it at 0%, though!)

I've advocated super-imposing progress bars on files in the past, and I
still think it would be a Good Thing.  I want it for a more general case
than just copying files within Nautilus, though.  It would be great if
any program that writes files (particularly those that download files)
could plug into Nautilus for this.  Anybody with a good solution to this
will get a big Attaboy from me.
