Father’s Day and Color Vision

Color Vision. In the past 15 months or so I have spent a lot of time, both in thought and in working with color, on this topic Considering that I have lived with severely red deficient vision people all my life, 15 months – so far – devoted to the topic isn’t very long. But, it did take a lifetime of learning to even be able to frame the question, “what do ‘colorblind’ people see?”

The question began as, “what does my son see? How does he see the world?” In working with him to answer that question, I learned a lot about my father, who also saw the world the same way. The results of that initial work with severe red deficient vision are available at Amazon in “Seeing Color Colorblind,” in both Kindle and paperback formats.

Ten percent of the US population is thought to have color deficient vision of some type and degree. Only about 1 in 200 women is colorblind. That is a lot of people who see the world differently from those of us with “normal” color vision, or fully functioning L cones (roughly red), M cones (roughly green), and S cones (roughly blue). The three major (although not the only) types of color deficient vision are Red Deficiency, Green Deficiency, and Blue Deficiency. People sometimes refer to Red-Green Colorblindness, but, in reality, someone with a red deficiency sees the world quite differently from someone with a green deficiency. I am now addressing the three major types in my current work.

The work is intriguing. Just as in the red deficiency work, I am bothered by the appearance of people. The red deficiency, in which skin tones are a cyan, bother me the most. I think this is because I am a physician, and a cyanotic appearance in a patient is never good news for anyone. But, the skin tones with the other deficiencies also bother me a little. The yellow skin tones through blue deficiency make me think “liver disease.” I cannot help that initial response. So, I limit the amount of time in a day that I will work on skin tones.

When I start to work on an image now, I have a pretty good idea how it will look to people with different color vision. But, every now and then, I am surprised how beautiful something seems to me, regardless of color. This image from the 2015 Corrales Garden Tour is one that really surprised me. I find it beautiful in all of the versions.

I think my father would feel more honored on this Father’s Day by images that show people with normal color vision how the world might appear to people with different types of color vision deficiencies than by the posting of an image of him. I thought this image was so pretty in all of its colors that I decided to use it for a Father’s Day greeting.

Happy Fathers Day to all!

Color and Light

Color and Light. Color Is All About Light

Color and light. The beauty of New Mexico is all about light. Sunrise and sunset are all about light. Rainbows are all about light. Photography is all about light. Color is all about light.

People see light differently. Those of us with “normal” color vision see one thing. But now I ask myself about almost everything, “How would that look to this other person or that other person?”

Albuquerque is known for the rather frequent occurrence of double rainbows after early evening storms, and last night timing produced a real beauty, a full arc double rainbow, one of the most magnificent I’ve seen in several years. I could not help wondering how it would look to people with some of the color vision deficiencies.

The upper left hand corner is how it appeared to me; upper right corner how it would appear to someone with a mild-to-moderate red deficiency; lower right a mild-to-moderate blue deficiency; lower left a mild-to-moderate green deficiency. They are all remarkably beautiful to me.

Double Rainbow – Color is All About Light

Again, the color deficiencies in this quadtych are mild-to-moderate, which is actually more common than near-complete absence of a color. Note that the objects on the ground, such as the trees and houses, are a little different in color to people with the different types of deficiencies that are only mild to moderate. But look at the difference in the sky!!!! The sky is all about light, and even mild color deficiencies make a huge difference!

Some of you who are my readers know that my view of the sky and events in it can be very different from the view of friends living only a few miles to the west, on the other side of the Rio Grande. Take a look at my friend Tim Price’s images of the same storm.
