Colour Contrast Checker

The colour contrast checker is a tool to test the contrast suitability of background colour and foreground text, to ensure your design colours meet the WCAG contrast ratio formula test.

With easy to use slide-bars to select colours according to hue, saturation and lightness for both background and text, the colour contrast checker will assess whether the colour combination is suitable for large and/or normal text.
