Description

Elements must meet minimum color contrast ratio thresholds. Detected by axe-core rule color-contrast on 87 of 1997 scanned pages (87 instances).

Steps to reproduce

Open https://www.luton.gov.uk/news/2025/medieval-action-adventure-returns-st-georges-day-celebrations.
Locate the element: .news__date > span
Confirm the axe-core finding for rule color-contrast against WCAG 1.4.3 Contrast (Minimum).

Impact

Affects Limited vision (2.4%), Without color perception (4.5%).

Limited vision — 2.4% of population
Without color perception — 4.5% of population

Affected pages

87 distinct URL(s) in the stored evidence. Query variants remain distinct. The URL evidence is complete; the list below may be a sample.

…and more — all 87 pages (CSV).

Testing environment

Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

Suggested fix

How to fix: Increase the contrast between text and its background to at least 4.5:1 (3:1 for large text). Check both light and dark modes.

Drupal tip: Check your Drupal theme's base CSS. Themes like Olivero and Bartik have contrast issues in default color schemes — override failing color pairs in your subtheme's style.css.

Suggested fix

How to fix: Give the link discernible text. Avoid empty links and icon-only links without an aria-label.

Drupal tip: "Read more" links from Drupal Views should use the "Link text" rewrite field to add context, or add aria-label via the Views rewrite output.
