Take a hatch door to your paint supplier. They can easily match the color.
You
WILL have sticker shock just buying the base coat paint and clear coat. Then there is the prep including any bodywork and then labor for painting the truck. To do it correctly, you will be looking at 6 to 10,000 dollars, additional custom paint work will add even more.
Just a comparison - I was quoted $6K to just spray a totally to the last part disassembled Model A Ford roadster. I was to supply the paint and do all of the prep work and car reassembly. I got to be a really good painter and did the job myself for less then $2K including a $400 pro level IWATA spray gun
If that cost is OK with you, then please do it and when complete, post photos of the job
