Yes. Emacs *could* color the foreground and background differently, but
I don't believe it should (users are free to customize things however
they like, of course). Every terminal emulator I'm aware of uses the
same palette for foreground and background colors, so I think we should
follow suit.
Instead, the goal should be to ensure a reasonable level of contrast
between commonly-used color pairs of different foregrounds/backgrounds.
At minimum, SGR white or black on any of the other basic colors should
be readable.
I don't think there's a bug here.
