ColorRite will have your touch up paint. I can tell you that your '98 Shadow ACE Deluxe is Pearl Canyon Copper/Gloss Black.
I've got a '98 too but its Pearl Sedona Red/Pearl Ivory Cream. I bought some of the Red from ColorRite and it matched perfectly.
edit: BTW, the 750 ACE Deluxe is an awesome bike and very dependable!
Are you guys sure? I’ve never seen that beautiful a shade of… peach?… on a stock bike. And looking at the feathers airbrushed onto the body of the tank, I’d say you’re looking at a VERY well-done custom paint job.
If you can find whoever did it and ask, they may have a few suggestions. Otherwise, most major paint places can use their optical system to get the shade, and make you up a small batch in a spray bomb or something…
