@Colin Watson: There already *is* an upstream-supported solution: grub2 has support for gfx, which currently is as easy as editing 3 lines (1 for the background image, 2 for the menu text colors) in /etc/grub.d/05_debian_theme. I know this because I've done it.
If a proper background image is made by the Canonical design team and appropriate text colors are used this could fairly easy be fixed I think.
