This is based on my failing memory of color-related aspects on X
window system; X gurus will excuse me if the below is a lie.

At least on X, there's a limited amount of color cells available to
all programs at any given time (unless programs use a private palette,
which most of them don't).  So, if some program uses up many colors,
Emacs might be unable to display all of the colors you expect.  But I
don't know whether defined-colors is affected by this.

In addition, on a tty, the number of supported colors can be changed
during the session.
