1) I don't understand your question. You may retake the color vision test utilizing any of the approved tests. If you pass one of these, send the results to the FAA and they will send you a medical without the color vision restriction. 2) I doubt an AME will accept an outside set of plates, they do not know the authenticity of the plates and whether or not they have been altered. I certainly would not accept them. 3) Yes, if they document the type of test and the number of errors on the test. The FAA has specific guidelines for each test.
