Pick any color visually and get instant HEX, RGB, and HSL values. Check contrast ratios and save a palette. Everything runs locally.
WCAG (Web Content Accessibility Guidelines) defines minimum contrast ratios between text and background colors to ensure readability for users with visual impairments. WCAG AA requires a ratio of at least 4.5:1 for normal text and 3:1 for large text. WCAG AAA requires 7:1 for normal text.
Use the contrast checker above to verify your color combinations before using them in web design. Good contrast is not just an accessibility requirement — it makes your content easier to read for everyone.
