What I normally do is run "emacs -nw" from xterm.  The CVS code has a
way of forcing Emacs on a tty to use 8 colors even if the display
supports more (some versions of xterm support up to 256 colors).
This option only works in a non-windowed session, thus -nw.

This might or might not be a good idea, I really don't know.  Suppose
the user really wants yellow on white--is it okay for Emacs to "know
better"?

For the default faces, this is already done manually: when the X
definition maps to something barely readable, like yellow on white, a
tty-specific definition is introduced with different colors.

Emacs has `list-colors-display' and `list-faces-display' which I
think greatly simplify the process of customizing face colors.  Isn't
that a worthy equivalent of a color cube you envision?
