Colorblindness and FALANT

[danielm]

I'm a colorblindness and took the FALANT test in argentina but i failed. The thing is that searching this problem on internet i realized that maybe this falant is different from the ones you've got. I say this because the colors in it are green, red, and yellow (instead of white, which i think you've got) Is this correct? are the colours of falant green, red and white?
Have anyone take other alternative test for colorblindess acceptable for FAA?
I tried red colored contact lenses and can easily see the Ishihara plates. I suggest everyone should try them on, but is it acceptable for aviation?

FALANT is red, green, and white. There are nine test plates (two colors at a time which can be any any combination including two of the same).

There are doctors around that have a battery of tests that are acceptable to the FAA. The other option is a control tower light gun. Doctors on the red board frequently put out referrals.
