The idea of this theme is to keep things simple and efficient, but it does have some of its own secrets to make super cool.
Humans have three kinds of color receptors in our eyes. If only two kinds are working properly, the result is color blindness. Some animals — reptiles and birds among them — are speculated to have four: they’re tetrachromats, and can detect color in the ultraviolet range, with wavelengths too short for humans to see. But some humans may also be tetrachromats.
Due to genetics, some women may be born with two kinds of red receptors, making them tetrachromat. They won’t see wavelengths we don’t, but if the brain can accomodate the fourth stream of data from the eye, they may be able to distinguish colors within the spectrum we do see far better than any of us. To a true tetrachromat, we may all be as the colorblind are to trichromats.
Here was the final route. 3,129 miles completed in about 5½ days, averaging about 10½ hours a day and loving every second of it. I wasn’t bored once and I could have done it with my phone turned off. I have no idea where I’ll be next summer but I’ll be sure to take the long way there.
