Green Go / Sassy Grass Green
Sometimes when I'm unsure or don't have a code. When color matching paint I take the gas door off and bring it to the paint supply. They have a scanner that usually gets the color very close, sometimes on the money. It depends on the color, how perfect it needs to match, if blending or panel painting. Always clean the panel with a 3M perfect it compound and glaze to bring up the color to as close as it was when originally sprayed. Hope that helps a bit.
BTW that is a beautiful Demon.
