That's what I did. I took the belt shroud from my 1998 PM 64A table saw to the local hardware store, they used their optical paint color scanner, and they nailed the bile green color almost perfectly. It's so close that even if you use it as touch-up paint, you can barely distinguish the difference.
FWIW, the brand and model of paint they used was "X-O Rust Interior/Exterior Oil Base Direct-to-Metal Enamel."
