Why Color Contrast Matters for Accessibility

Good design isn't only about looking modern — people need to read your text. Low contrast between text and background is a top accessibility failure on the web.

WCAG contrast basics

• AA (normal text) — at least 4.5:1 contrast ratio
• AA (large text) — at least 3:1
• AAA — stricter (7:1 for normal text)

How to check

Pick your foreground and background colors, then use a contrast checker. Our free Color Tools include HEX/RGB/HSL conversion and a WCAG contrast checker so you can fix issues before launch.

Quick tips

• Avoid light gray text on white backgrounds
• Don't rely on color alone to convey meaning
• Test buttons and links, not just body text
