That's because for graphics displays, the same approximation is done
by the C function x_alloc_nearest_color_1.

`tty-color-approximate' is not a user-level function, in general.

How did you think to do that? I don't think there's a solution for
this problem, since the full set of colors known to the window system
is unknown to Emacs (the colors that are produced by
`list-colors-display' are taken from a partial list that might be only
a tiny fraction of the full list).

If we want to add something like that, I'd rather go for a
full-fledged color selection cube, where one can select a color by
moving the mouse pointer, similar to what some X applets let you do.
