If you want to permanently change DOS to use a different color, you can patch
COMMAND.COM to clear the screen differently.  Use DEBUG to search COMMAND.COM
for all INT 10 calls, CD10h.  Find the one which is CLS (where it scrolls the
screen 25 lines) and patch the byte that it loads into BH, which controls the
color.  This should work on any DOS version, even OEM and weirdo versions.
