Which color vision test is preferred?

My memory was telling me that Farnsworth Lantern test was preferred to get
a waiver. Since that no longer seems possible, I'm looking for options
here. I read today that a Dvorine or AOC test is preferred. Can anyone
confirm that? Recommend another? Are these tests hard to find? What's
available in the Dallas? Obviously, I'd like to try to shop around some
of these tests without involving the FAA, before I have to use the light
gun test as a last resort.

I do suffer from a mild form of deuteranopia. Is there any statistics on
the number of pilots with this type of color blindness which have
successfully obtained their waiver/exemption? I remember reading, over a
year ago, some document from the FAA which gave some statistics, but I no
longer remember the break out.
