Color Background Calculator

Color Contrast Calculator is a tool that helps you determine the contrast ratio between the text color and the background color on your web page. It calculates the contrast ratio based on the formulas recommended by the Web Content Accessibility Guidelines (WCAG), which state that the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text (18pt or 14pt bold). By using this tool, you can ensure that your website's text is easily readable for those with visual impairments or other disabilities.
