code of body paint color....

I own a 1998 trans sport montana and I need repair it some light damage of the exterior body paint. I know that the paint code is in the chart placed in the plastic door of the compressor air system (placed rear at left side).
The problem is that in that plastic door there are many numbers and letters (codes)....

Somebody knows what is the position in this "chart" of the body (exterior) color paint code?

I will appreciate your help.....
