color blindness and the like
All you need to know color-wise is the difference between red, green, and white. The tri-chrome plates are a bit excessive in my opinion and if you're nervous about the test it is helpful to look at examples beforehand just to get a feel for the test. And contrary to what you may think your tester will most likely help you out if you just made a careless error by saying something like, "are you sure about that one?" In closing, if you're not profoundly color blind you will pass the red, green, white test so go to a hospital that does that one instead of tri-chrome if you can.
