That's because the documentation is not up-to-date with the Debian
patches additions. Those options are really handled, they really have an
effect (I tested it). I learned about them while reading:

  http://www.katspace.org/computers/Grub_Splash/

This option is added by the Debian specific patch
debian/patches/graphics.diff. Here is the definition of the foreground
option in Debian's patch:

+static struct builtin builtin_foreground =
+{
+  "foreground",
+  foreground_func,
+  BUILTIN_CMDLINE | BUILTIN_MENU | BUILTIN_HELP_LIST,
+  "foreground RRGGBB",
+  "Sets the foreground color when in graphics mode."
+  "RR is red, GG is green, and BB blue. Numbers must be in hexadecimal."
+};

Best regards,

Thomas
