    A video explaining first why human eyes are sensitive to light between 380-750 nanometers in wavelength when light can be so much more varied in wavelength. The brief answer is that the light the sun produces (and that isn't also absorbed by Earth's atmoshpere, though he doesn't mention that) is mostly in these same visible wavelengths. He then explains how human color sensitivity works and why we have our RGB cones, and talk a bit about how there are tetrachromats who have 4 cones who can see colors in more detail becauss of it.
