I'm red green color deficient. I can see vivid green and red like a stop light. I have a real problem with pale green, pale red and differentiating olives from browns.
I knew I was red green color blind from looking at the color vision tests in books.
During Vietnam I had a draft physical, a Navy physical and an Air Force physical. The color vision test for the draft was sticking my head in a box with a red light and a green light I passed. For the Navy, the test was a box with a red light, a green light and a white light and I needed to look at it across the room. I failed and the Navy was not interested in me. I took the same test as the Navy for the Air Force and failed again. I wanted to be sent to computer programming school after basic training. When I was given my school assignment, it was to be a photo interpretation specialist. Some one had recorded 15/15 instead of 0/15. Since I couldn't be a photo interpretation specialist, I was told I could pick whatever training I wanted. I asked for programming school and was denied probably because I already had taken a few programming classes and they wanted people without nay training.
I ended up as a computer operator and when I was discharged I got a job as a programmer trainee, partially because of my experience as a computer operator. I retired after a 40 year career as a programmer.
My mother was also color blind and her job was designing patterns for fabrics. My wife, who went back to school and got a degree in studio art has exceptional color vision. She saw sample work that my mother did and shook her head. It looked good to me because my mother and I were both color blind.
It's all not hard for someone my age to imagine what it would be like seeing the world in black and white. I watched television in black and white for many years before I watched color tv. When the Wonderful World of Disney broadcast in color, they splashed color all over the screen. I still saw it in black and white. I started working with computers around 1970 and the screens at work were black and white along with the printout. The first time I could see a color display at work was after 2000 and that would have been the internet.
Color photography has been around for a along time but it took quite a while to be accepted as an art form.
