You are lucky in that you have a one off truck. They appearently used the wrong paint on it when it went through the paint booth. Have them document it for you in some way. See if you can find the paint code for the color you have.
Now for the fix. As long as the scratches are not through the clear coat you are okay. If the they are through the clear coat the only fix is to repaint it. Anyway, if it's clearcoat only they can prep the surface and reshoot the clear and you are as good as new. Actually better in a way.
Remember oddball mistakes sometimes become valuable in the future. The important thing is the documentation that it came from the factory that way.
Good luck.
