Can you easily remove a panel/compartment door etc? If so take it to a good local auto body paint store, then can take computer reading of the paint color and then match it up exactly for you.
Stop by a CarQuest store and take in something like a removable exterior panel that has the colors you need. They will scan it and order custom paint in a spray can to match.
Look inside usually one of the upper cabinet door and should be a paint code. Or go to any good car paint store and they should be able to scan the color and come close.
