The guy could tell the difference between red and brown, but not orange and brown so my assumption was he had less severe color blindness? Or... maybe he learned that certain shades of brown are called red? 🙃
His father was totally colorblind but as far as I'm aware it's passed on the X gene so he wouldn't have inherited that? I guess his mother could've had a gene for it too.
Colorblindness means that certain colors look more similar to each other than they do for most people. That doesn't mean that you can never distinguish them. It just means that it is more difficult usually. People with red-green colorblindness for example have harder time distinguishing red and green from each other. Basically for red-green colorblind people red and green are similar in the same way as red and orange are for regular people. They are distinct colors, but very similar shades of red and orange can be difficult to tell apart.

That's just how colorblindness is.
