Funny thing... I'm sorta half-assed color blind.
In bright sunlight, maybe I can read the colors, or close enough. If I'm going to use a resistor in a circuit, I measure it. Used to be with a VOM that used vacuum tubes, but today, the digital ones work as well or better.
I got into the military on a waiver for the color-blind thing. Both times.
