How to fix: Low color contrast
Low color contrast is a common WCAG AA accessibility failure that automated scanners flag and that EAA enforcement authorities take seriously. Here is what triggers it, why it matters, and the concrete fix.
Why it matters and how to fix it
Users with low vision cannot read text that blends into the background. WCAG 1.4.3 (Contrast Minimum) requires a 4.5:1 ratio for normal-size text.
Increase the contrast ratio to at least 4.5:1 for normal text and 3:1 for large text.
Re-run the scanner after the fix to confirm zero violations on this rule. Add a unit or e2e test that asserts the relevant attribute is present so the issue cannot regress silently.
Guidance, not legal certification
Scan results are automated accessibility guidance, not legal advice or a certified conformance opinion. Always pair an automated scan with manual expert review.
Frequently asked questions
Will my site be fined just for this issue?
Single issues are rarely fined directly. Authorities usually require remediation within a deadline; ignoring the notice can lead to administrative fines.
How does the scanner detect this?
We run axe-core rules against the rendered page and surface every violation with the matching WCAG criterion and the impacted DOM selector.
