After the jump: AZPM's Heather Gray reports on Tucson photographer Michael McNulty's study of how the human eye sees color:
From behind the lens of his camera, Michael McNulty became curious about the rich colors of the desert, so he began to research the properties of light, and how the human eye sees color.
"One way to define light is that it’s the part of the electromagnetic spectrum we can see," McNulty said. "But that’s a really tiny, tiny portion of the whole electromagnetic spectrum."
"We don’t necessarily think we have trouble looking at red and blue, but if you try to look at different shades of red and blue, you’re going to find that you cannot distinguish them as well as you can green," McNulty said.
McNulty shares his stories of red, green blue in this segment of AZ Illustrated Science. He is working on a book based on his research about the colors of light.
