I’m color blind. Initially diagnosed as red-green color blind at an early age, gradually I came to learn that I have a related, less severe case of purple-blue color blindness. And those challenges bleed into other shades.
I imagine we all see color differently.
I can see colors. No problem with traffic lights, red and green look different. Maybe they don’t look like the red and green that others see. It’s when red and green dots are close together that the differences fade away.
