On our 2004 Marquis, the exterior paint colors and their "part numbers" are printed on a sheet and affixed on the back of a kitchen cupboard door. And as Steve pointed out, usually all the exterior colors are painted onto the exterior access panel behind the fridge. If you do not find the colors elsewhere and the color is on the access door, then take the access door behind the fridge to the paint shop. The exterior paint colors on our Marquis were made by BASF/Diamont. I believe BASF/Diamont was required to stop that paint formulation though. Several years ago I got four pints of our four exterior colors for touch-up purposes from the local paint supplier to the Beaver/Monaco manufacturing facility in Bend, OR.
