What is Non-Text Contrast?
WCAG 2.1 Success Criterion 1.4.11 requires a contrast ratio of at least 3:1 against adjacent colors for:
- User Interface Components (e.g., focus indicators, borders of input fields)
- Graphical Objects (e.g., icons that convey meaning, parts of a chart)
This differs from the 4.5:1 ratio required for standard body text, as graphical elements are typically larger or have more visual weight than a single character of text.
