I don't think that really matters. There could be just empty variable
in /etc/default/grub, or that variable may contain some special
keyword ("none", "empty” or "blank" comes to mind). I think that you
should choose the one that you find the easiest in implementation.

What is more important, that option should be somehow documented, at
least in grub-pc's README.Debian file.

I don't think that one was around when I was filing my bug report, but
that's alright. Just wanted to point it out by the way.

Since you are considering there moving GRUB_BACKGROUND_COLOR_NORMAL
and GRUB_BACKGROUND_COLOR_HIGHLIGHT into /etc/default/grub, you should
also consider deleting /usr/share/desktop-base/grub_background.sh
file. Right now that file contains variables for splash image and
colors. If these variables were to set in /etc/default/grub (which I
find much more intuitive), there would be no more need of
grub_background.sh file.
