Text contrast (text-contrast)

Text smaller than 18pt (or 14pt bold) must meet a contrast ratio of 4.5:1 against its background.


Insufficient text contrast 2.1:1:

This paragraph has black text with 30% alpha transparency on a white background. Its contrast ratio is 2.1:1, which fails WCAG minimum contrast requirements.


Some text in English

Note: Possible to implement because contrast ratio can be programmatically calculated using rendered color values and compared to the minimum 4.5:1 threshold.
