Colour Contrast Checker is a tool designed to evaluate the contrast between different colour combinations according to WCAG standards. By simply entering background and foreground colours, users can instantly get the contrast ratio and see if it meets the accessibility guidelines for different levels (AA and AAA) for both normal and large text.

This tool features intuitive controls that allow users to adjust the colours in RGB or HSL formats, reverse the colours, and save their chosen palette. Additionally, it provides real-time example text to see how the colours perform in practical use cases, making it easier for designers and developers to create accessible and visually appealing content.
