Statistically, there have to be a few dozen colorblind people on this
list. I was wondering if anyone knows of any test kits for Ca or GH that
are readable for us colorblind folks. I am having a hard time
determining my Ca levels. Turning from light green to an orangish-red is
not detectable to a red-green colorblind individual - nor is light blue
to light pink as GH and Ca tests generally are respectively.
