Yes, sorry for the typo.

I know that the list of colors displayed by list-colors-display on X
is fixed (see my message earlier in this thread), but I always
thought, I don't know why, that the length of that list is near the
number returned by display-color-cells.
If this is not true, one may ask what is so ``interesting'' about the
specific colors we show as opposed to those we don't. For example,
when I work on Irix, I generally like to use the Irix-specific colors
(that are not shown by list-colors-display, of course) because they
are much more pleasant to my eyes. So to me, those unshown colors are
much more ``interesting'' than those we show, in that specific case.
The importance of list-colors-display is that some people use it to
choose colors for their customizations, so the shown colors need to
have some resemblance to what Emacs can support.
Bottom line is, I think list-colors-display should display colors
whose number is close to what Emacs can use on that display, except
that it probably shouldn't be too long (so I don't suggest to display
64K colors, for example). Perhaps a short comment to the effect that
we are showing only N out of possible M colors would be good there.
But this is not the gravest problem with this issue; see my other
messages about the value returned by display-color-cells, which I
think is the main issue here.
