Vladimir suggested on IRC that I should generalise the gfxmenu colour
parsing code instead. Here's a patch that does this. I've pushed this
to the parse-color branch here:
bzr+ssh://bzr.sv.gnu.org/grub/branches/parse-color/
2010-12-10 Colin Watson <address@hidden>
Move gfxmenu color handling to video, so that gfxterm can use it
too.

* grub-core/video/colors.c: ... here. Rename
grub_gui_get_named_color to grub_video_get_named_color.

* grub-core/Makefile.core.def (kernel) [videoinkernel]: Add
video/colors.c.
(gfxmenu): Remove gfxmenu/named_colors.c.
(video_colors) [videomodules]: New module, containing
video/colors.c.
Add a background_color command.
