Tool usage guide
The Color Accessibility Checker is a professional utility designed to verify if your chosen foreground and background color combinations meet WCAG contrast ratio standards, ensuring your digital content is readable for all users.
Background
Designing a call-to-action button with a specific brand blue background and white text.
Problem
Need to confirm if the white text is legible enough on the brand blue background to meet accessibility standards.
How to use
Input the brand blue hex code into the background field and white (#FFFFFF) into the foreground field.
Outcome
The tool confirms a high contrast ratio, ensuring the button is accessible for all users.
Background
Implementing a new dark mode theme for a blog using a dark gray background.
Problem
Unsure if the chosen light gray text provides enough contrast against the dark background.
How to use
Input the dark gray background hex and the light gray text hex to verify the ratio.
Outcome
The tool identifies that the contrast is too low, prompting an adjustment to a lighter text shade for better compliance.
For normal text, WCAG AA requires a contrast ratio of at least 4.5:1, while AAA requires 7:1.
This tool currently supports standard solid hex color codes.
Proper contrast ensures that users with low vision or color blindness can distinguish text from the background, preventing eye strain and improving readability.
The result provides the calculated contrast ratio and indicates whether the combination meets AA or AAA compliance levels.
This tool is designed to check one specific foreground and background pair at a time for precise validation.
