How to fix color contrast on WooCommerce

Steps for WooCommerce

1. In WordPress admin go to Appearance → Customize → Colors (or your theme's color section). If your theme provides a color picker for body text or link color, update it there.
2. If your theme does not expose the specific color, go to Appearance → Customize → Additional CSS and add an override rule, e.g.: `a { color: #005f8e; }` using a shade that passes 4.5:1.
3. For block themes (Full Site Editing), go to Appearance → Editor → Styles → Edit Styles → Colors and update the global palette entry for the failing color.
4. If you use a page builder (Elementor, Divi, etc.), open its Global Settings / Theme Builder and update the color token in the global color palette.
5. Save, then use Chrome DevTools (F12) → Lighthouse → Accessibility to verify no contrast failures remain.

/* BEFORE — fails WCAG 4.5:1 on white background */
a, .link-color {
  color: #007fbf; /* contrast ratio ~4.38:1 on #ffffff */
}

/* AFTER — passes WCAG 4.5:1 on white background */
a, .link-color {
  color: #006699; /* contrast ratio ~5.06:1 on #ffffff ✓ */
}

/* Tip: use a CSS custom property so one change fixes every instance */
:root {
  --color-link: #006699;
}
a, .link-color {
  color: var(--color-link);
}

What is color contrast?

Color contrast is the difference in brightness between the color of your text and the color of the background behind it. Web accessibility guidelines (WCAG 2.1 Success Criterion 1.4.3) require that normal-sized text achieve a contrast ratio of at least 4.5:1, and large text (18pt/24px or 14pt/18.67px bold) at least 3:1. A ratio of 4.38:1 — like a medium blue (#007fbf) on white (#ffffff) — falls just short of the normal-text threshold. The fix is simply choosing a slightly darker (or lighter) version of the color so the ratio clears 4.5:1.

Roughly 1 in 12 men and 1 in 200 women have some form of color vision deficiency, and millions more have low vision or read in poor lighting conditions. Text that fails the contrast threshold is genuinely hard to read for these shoppers, directly reducing conversions and increasing bounce rates. Legally, WCAG 2.1 Level AA is the standard referenced in ADA, Section 508 (US), EN 301 549 (EU), and equivalent laws worldwide — failing it exposes your store to demand letters, complaints, and lawsuits. Search engines also reward accessible, readable pages, so fixing contrast can have a small positive effect on rankings.
