The problem i have with all these different tests is that they dont have a practical basis.
Ok if I am going for a job reading numbers in colour dotted books then that would be an excellent tool for seeing how good I would be at it.
If my job is determing shades of green foliage in trees then thats what my test should be.
Aviation colour tests should be based on how practically you can determine colours that are used. Ie in a simulator or simulated viewing device or even actual aircraft you should be tested in a practical way on whether your colour vision poses any problems in the real world.
