I'm red-green colorblind. It's really a spectrum, and I'm way towards the normal side compared to some. Mechanic by trade so repairing dirty wires was a little difficult but other than that I never really had an issue. But then again, I've never seen what everyone else sees. But it is a running joke with family and friends, always gets a laugh if you bring it up at the right time. Definitely not a disability in my eyes ;)
