2. This is the best way. You can go take a Farnsworth Lantern test. There are VERY few of these around, but you can find them. If you pass it (it is WAY more accurate than the dot book test) you get a letter from the FAA that you bring to all of your medicals stating you have already passed the color test, and that you NEVER have to take another one. This is NOT a waiver or a SODA, as it specifically states that on it. You never have to let any employer know about it, even if they ask if you have any waivers or SODAs.

If you have any questions let me know. I went through this a few years ago, so I am versed in the process with the FAA.
