Color Blind Test
A pattern-finding game inspired by Ishihara-style dot plates. Find the hidden number in each plate and see how many you can identify.
A pattern-finding game. Not a vision test or medical screen — for any concern about how you see color, talk to an eye-care professional.
You will see 10 dot plates. For each plate, type the number you see or indicate that no number is visible.

How It Works
- Click Start to begin the color vision screening.
- A circular plate filled with colored dots appears. A hidden number is formed by dots of a different color.
- Type the number you see, or click “I can't see a number” if nothing is visible.
- Continue through all 10 plates. Each tests a different type of color distinction.
- View your screening results and interpretation.
Understanding Your Results
This screening uses plates designed to test different types of color vision. Control plates should be visible to everyone. Red-green plates test for protanopia and deuteranopia (the most common forms of color blindness, affecting about 8% of men and 0.5% of women). Blue-yellow plates test for tritanopia, a rarer form of color vision deficiency.
Missing multiple plates of the same type may indicate a specific color vision deficiency. However, screen calibration, ambient lighting, and display quality can all affect results. This screening is not a substitute for a professional eye exam.
Tips for Accurate Results
- View the test in good lighting — avoid glare on your screen.
- Use a properly calibrated display with brightness and contrast at normal levels.
- Do not use night mode, blue light filters, or color-adjusting software during the test.
- If you suspect a color vision deficiency, consult an eye care professional for standardized Ishihara or Farnsworth testing.
