Sometimes people see the world in black and white because they don’t have special color sensors in their eyes. Just like a black-and-white photo only has shades of gray, these people only see those shades instead of full colors. Their eyes work like filters that let through only certain parts of light, sometimes just black and white.
Examples
- When they watch cartoons, everything looks like an old TV show from the 1960s.
