Squirrelluck,
No apology from you is necessary. You see, I suffer from MS. I no longer even try to "educate" people about the effects of this disease on me. Like your color blindness, if you don't have it, you just wouldn't understand.
However, I commend you for overcoming your issue of colorblindness. You see, you have found a way to rise above it. You know that you can track a wounded animal...or find help in doing it. The "other guy" is just plain lazy and uses his disability as a poor excuse.
