Color Vision Test
An Ishihara-inspired screening to check for common color vision deficiencies. Answer 8 plates — identify the number (or lack of one) in each pattern.
Before you start
- Use a well-lit room — no glare on your screen
- Set screen brightness to full and disable night mode
- View from 50–75 cm (20–30 inches) away
- Do not zoom in — view at 100% size
Calibration check:
You should see three distinct colors: red, green, blue.
