WCAG Contrast Checker
Designing a website that looks good is one thing, but making sure it’s easy for everyone to read is even more important. Our WCAG Contrast Checker helps you make sure there’s enough contrast between your text and background so people can easily see and read your content—especially folks with visual impairments.
This tool checks your colors against the Web Content Accessibility Guidelines (WCAG), which set the rules for making websites more accessible. Whether you’re picking colors for buttons, headlines, or body text, this tool helps you get it right.
What it does:
Instantly checks the contrast between your text and background colors
Tells you whether your colors meet WCAG AA or AAA standards
Shows you pass/fail results for both normal and large text
Works with HEX, RGB, or custom color inputs
Why it matters:
Good contrast isn’t just about looks—it helps more people read your site easily. Whether someone has low vision, color blindness, or just prefers higher contrast, this tool ensures your site is welcoming and accessible. Plus, it helps you follow best practices for accessibility.
No more guessing. Just plug in your colors and get instant feedback to make your site more inclusive and user-friendly.
Good vs. Bad Contrast Combinations
Black text on white background#000000 (Black) on #FFFFFF (White) – Clear, easy to read
Dark blue text on light yellow background#003366 (Dark Blue) on #FFEB3B (Yellow) – Great contrast and very readable.
White text on dark gray background#FFFFFF (White) on #333333 (Dark Gray) – High contrast and clean look.
Bad Contrast (Fails WCAG AA Standards)
Light gray text on white background#D3D3D3 (Light Gray) on #FFFFFF (White) – Too faint, hard to read, fails contrast check.
Yellow text on light green background#FFFF00 (Yellow) on#90EE90 (Light Green) – Not enough contrast, very difficult to read.
Light blue text on white background#ADD8E6 (Light Blue) on #FFFFFF (White) – Too light and not readable for many users.
Tip: When checking contrast, remember that WCAG AA is for general web content, while WCAG AAA is the highest standard, perfect for making sure your site is as accessible as possible to all users.
