I give a lecture on Accessibility in my Software Engineering course each semester and at a recent faculty retreat since I have to rework the course materials for every new course I teach. I am a colorblind photographer (protanopia or red deficient). I didn't find out until I failed the flight physical for the USAFA. There were indications that became more apparent at that point. I see some red, but have trouble distinguishing yellow/green, blue/purple, and cyan/white.
Computer displays can cause trouble, particularly with dark mode. When students come to me for help with a dark mode screen, I tell them they can close their laptop. After my lecture, they understand why. I made some suggestions to correct the colors on the last revision of CR so I could use dark mode, looks like I'll need to go back to light mode for now. Here are some views of the new CR site adjusted for different types of color blindness. Red text and highlights on a dark background are particularly bad for me as you will see. The percentages are for the US population, where about 8% of the population is color blind, mostly males.
