You know, I never really realized it before you put it into words, but you're right. Not seeing some colors as well or at all is something, but the most confusing thing, usually both for me and other people, is how they're able to precisely categorize almost any color into a discrete group, and I have a very hard time doing that. I'm also in the same boat as to "what should we do about it". At least it's something that's easy to explain to people and well known. I always wonder if there are not lots of people going around that perceive things in very different ways than other people, and have no way of knowing if it's just us. You can test colorblindness with the plates, but what if all food tastes off to you, how do you test that? Or if human voices tend to sound like screenching? Your point about colors vs shape is also interesting. I wonder if the fact that I'm colorblind plays into my preferences of terminals, text and keyboard shortcut.
