Not sure if mine is the same color, but my 93 Sable is called Clear Crystal Blue Frost.
The two letter exterior color code is MD and the Dupli-Color code is DSFM320
I'm attaching a pic so you can see the color
Look on the tag in your door jamb - it should have a two letter exterior color code. Go to a local dealership and ask them what name goes with that color code(or pretend to buy some touch up paint, get the full name with the code, and then punk out h34r: )
