By "Do nothing" I mean, if I were to hit tab and attempt to complete
the list of colors available for a face, I'll see something like this:
Possible completions are:
black                              blue
brightblack                        brightblue
brightcyan                         brightgreen
brightmagenta                      brightred
brightwhite                        brightyellow
color-100                          color-101
color-102                          color-103
....
color-96                           color-97
color-98                           color-99
cyan                               green
magenta                            red
white                              yellow

Where those color-# goes from color-16 to color-255.

Selecting one of these colors, say, color-200 results in the color of
the face being white, as if nothing had happened.

That could easily be true. I set my termcap to be the one provided in
the xterm distro and it didn't seem to help, though I could have
messed something up, I'm sure.

Well, like I say, it displays 256 colors just fine using the perl
programs that are in the xterm distro.

That's all I'm using. The link was just a point of reference.
