we ended up with another cone sensitivity right next to the other one. They're exactly side by side in a really weird, peculiar way. Why would you want to have a third cone sensitivity the same part of the spectrum? It's just like 15 nanometers away.

All right. So I realized later that when you look, you know, I've noticed that one of the things that matters is blood under the skin, blushes, blanches, health modulations. All of these kinds of emotions, signals that humans and other primates are doing on bare skin is shown by virtue of the blood of the skin.

And it's by virtue in particular of the oxygenation, deoxygenation of hemoglobin under the skin. And it turns out that when you're looking at the completely arbitrary and weird spectrum of hemoglobin, which is a bunch of, it has a little W in one, this one part. So it goes like this, and there's a little W. And when it's, that's when it's oxygenated.

So it goes like this, and there's a little W. And when it's, that's when it's oxygenated.

And when it deoxygenates, that W in that little region turns into a U. And so these little peaks right there in the W part If you wanted to be sensitive to this oxygenation, deoxygenation, you actually have to have two cones right there.

So the little W peak in the middle, as it goes down in terms of you and the other parts that go up, you have to sense that you have to have a peculiar spots of two cones in this exact spot.

So I was like, oh my God, exactly where you'd have to put cones to be sensitive to the only spot where you could tell that it's getting oxygenated versus deoxygenated is exactly in the spots where we have our cones.

So this is an empath sense. In short, our color vision, our primate color vision is an empath sense. It's only by virtue of that that we can see these blushes and blanches. And it's only by virtue of that that you can actually see veins at all. The veins, of course, are the deoxygenated parts. And the more fleshy red parts are the more oxygenated parts.
