I'd recommend taking a cabinet door that is the color you're trying to match and the piece of wood you're going to stain and have a "sit down at Sherwin Williams" with a "Pro" .... The "guy at Ace" or the "gal at Lowe's" likely won't have the same amount of experience and your results will show their level of knowledge.

Even if you get the "same specific contact paper by color number and grain" on a 5-10 year old trailer, the sun bleaching that has affected the old contact paper and what you now buy as "the same color" will not match. You're going to have to find a "pro that can work with the art form" who is experienced in color matching stains. It's not an "easy to do process" and just the species of your wood vs the "contact paper finish" will all come into play to make it impossible to match for the "kid at ACE or the part time worker at Lowe's"... talk to the pro at Sherwin Williams or another "industry paint store"....
