How contrast ratio is measured
The ratio compares the relative luminance of the text and background, on a scale from 1:1 (no contrast) to 21:1 (black on white). WCAG 1.4.3 requires 4.5:1 for normal text and 3:1 for large text; the stricter AAA level wants 7:1 and 4.5:1. Low contrast is the single most common WCAG failure and a frequent trigger in ADA website lawsuits — but it's also one of the easiest to fix.
