In the graph above, you can see the human spectral range compared to the one of a bird. As birds are tetrachromats, they see four colors: UV, blue, green and red, whereas we are trichromats and can only see three colors: blue, green, red. (UV light has no color and the bright pink was only chosen for visual representation.)
