Sorry couldn't be a 99 thats a twin cam,looking at the brochure i've got for 98 i think it must be midnight red and champagne pearl, there's no orange listed for 98.
It is not Midnight red and champagne pearl! The red and pearl are the anniversary colors like mine. It is possible that you have a factory custom color. Look under the gas tank and see if you can find a number that looks something like this. 1 of 400. There are some years that used special paint sets. Not sure where you could find the info listing what the colors are called though.
Your paint set was a limited edition, called 'creamsicle' by the public, not by Harley.
Here is a thread with a 98 Fat Boy, 7th posting down,
also, google 'harley creamsicle' and there are a few other examples.
Nice bike. I had an orange/black 01 WG and she sure shined in the sun.
