What humans see as red, another animal might see in shades of black and white or as a completely different color. Some animals see colors humans can't. Culture makes a difference in color perception, too. Until extensive contact with the West, the Japanese had no word for the color blue. No one can say.
Poets look differently at the world.
Artists do, too. Very much like our visual sensory system, they look carefully, tear apart what they see, then reconstruct visual meaning. I'm very visual. I watch people. I watch everything.
