Chainsaw Repair

I'm a pilot... I have to get that checked every two years (not sure why... color blindness is not supposed to change over time).

I have a very mild red/green color blindness.  Basically, I always pass the test, but there is some hesitation while I'm looking at the color plates.  I had no idea I even had the condition until I was tested for my pilot's license... I never have trouble distinguishing traffic lights or colors of markers or paper.

Red/Green color blindness is very common in men, and lots of men have it without ever knowing it.  If my problem viewing it was related to R/G colorblindness, then I would expect a number of your members would have had the same problem.

I have no deficiency at all in the blue spectrum (which is a much rarer form of color blindness).
