What is a Color Blindness Test?

The Ishihara Color Blindness Test uses images (Ishihara plates) with numbers hidden within circles of colored dots. It is a quick and simple way to screen for red-green color blindness.

This web-based test randomly shows 10 color blindness images. You are asked to choose the number you see in each image. Your total score helps assess your ability to perceive colors.

How to Use

1. Click the “Start Test” button to begin. One image will appear at a time.
2. Select the number you see in the image from the available choices.
3. You’ll immediately be told if your answer is correct or incorrect, and the next image will load automatically.
4. After answering all 10 questions, you’ll receive a summary of your results.

Notes
