There were 2 "green" colors for a Jeep TJ in 1998: Moss Green Pearlcoat (code RJN) and Bright Jade Satin Glow (code SQP).
There is a tag next to the drivers seat. The paint code is on the middle line, second set of letters/numbers. Will start wit a P..
PXR is the color code for the paint color of the vehicle. If you take that color code to a auto paint supplier they can match the color exactly. I believe that is a Jeep color code for Brilliant Black Pearl Coat.
To find the exact color of your Jeep, there are many places to look. In all models, you can find the paint code in the driver side door jamb, in front of the radiator, on the firewall, or under the driver seat. In Wranglers, you can check the driver side door and bottom deck as well.
Yes, I own a 94 and a 95 YJ the paint code is the same and because they are hard to tell apart aside from a tiny bit of sun fading.
