What do people with color blindness really see? 👁️🌈
Hi, I’m your Los Angeles ophthalmologist, and today we’re talking about one of the most misunderstood topics in vision - color perception.
A lot of people still think color blindness means seeing the world in black and white. That’s a myth.
In most cases, people do see color - just differently. Most commonly, the difference affects the red-green spectrum.
Color vision starts in the retina.
There are two key types of cells - Rods, responsible for light and night vision, and Cones, responsible for color and sharp detail
Your brain compares signals from different cones to create the full range of colors you experience. If one type of cone doesn’t function properly, color perception changes.
Here’s what that can look like:
🔴 Protanopia - reds may appear darker or muted.
🟢 Deuteranopia - reds and greens blend, making them hard to distinguish.
🔵 Tritanopia - difficulty distinguishing blue and yellow (much rarer).
Color vision isn’t just about traffic lights.
It matters for:
✔️ Designers - so charts, buttons, and interfaces are accessible to everyone.
✔️ Teachers - so color-coded instructions work for all students.
✔️ Doctors - when interpreting color-based test results and diagnostic charts.
✔️ Anyone who works with visual data.
Now it’s your turn.

Important: Online tests give a screening result, not a diagnosis. Accurate color vision testing requires professional clinical tools.
If you’ve ever wondered whether your color perception is normal - or if you want to check your child’s vision - schedule a comprehensive eye exam.
