Thoughts On Color Issues?

ok so I dont really care much about identifying stamps by color (though I may in the future) but how does one contend with being color blind? I ask this because I am partially color blind.. that is to say that my red spectrum does not register correctly so that shades of color either look the same or appear as another color.. for example purples and some blues look the same to me and shades of red look orange ... close shades are the hardest for me... so when we talk of shade variations how does one deal with this issue

I know there is another SCF member who has talked about this problem, maybe he'll chip in with some advice! I believe he generally uses his wife's eyes for the task!
