It's done! Go to the Karaoke Home Producer Download page at
http://mtu.com/support/downloads/khpro/code.htm (you will need your username-password to enter). Scroll down the page. You will find two files to download. Executing either on your system will change the Sweep color to that of the executed file, and the Border color is the same as the Background color for both files.
The technique we are using for this interim solution does not allow other colors. When we tried Fuchsia and Lime, they both came out the same as blue. Tried tweaking the colors but to no use. Anyway, you now have Blue or Red choices, in addition to the default Yellow.
