Color Contrast Checker - Accessibility Tool
Check color contrast from images to ensure your designs meet WCAG accessibility standards. Our contrast checker helps you create accessible designs that work for everyone, including people with visual impairments.
Why Check Color Contrast?
- Ensure WCAG 2.1 accessibility compliance
- Help users with color blindness
- Improve readability for all users
- Reduce eye strain for extended viewing
- Create inclusive designs
- Meet legal accessibility requirements
Understanding Contrast Ratios
Contrast ratio measures the difference between text and background colors:
- 4.5:1 - Minimum for normal text (WCAG AA)
- 7:1 - Enhanced contrast for normal text (WCAG AAA)
- 3:1 - Minimum for large text (WCAG AA)
How to Check Contrast
- Upload an image containing text and background
- Click on text color to extract it
- Click on background color
- Get contrast ratio and accessibility level
- Adjust colors if needed for better contrast
WCAG Compliance Levels
- Level A: Minimum accessibility standards
- Level AA: Enhanced accessibility (recommended)
- Level AAA: Superior accessibility (ideal)
Common Issues
- Light gray text on white background (insufficient contrast)
- Small text with low contrast (hard to read)
- Colors alone used to convey information (inaccessible)
- No focus indicators on interactive elements
