Colour Contrast Analyser: Free Colour Analysis Tool

Colour Contrast Analyser is a free tool by Paciello Group that helps check the colour contrast ratio between two colours to determine if they meet WCAG accessibility guidelines. It can quantify compliance with AA or AAA level colour contrast requirements.

What is Colour Contrast Analyser?

The Colour Contrast Analyser is a free application created by The Paciello Group to help web developers and designers test the colour contrast of text and background colours on their websites. Proper colour contrast between foreground and background colours is essential for an accessible website, allowing text to be clearly readable by users with various visual disabilities or impairments.

The tool quantifies the colour contrast ratio between two selected colours and evaluates if that contrast ratio passes accessibility standards set by the Web Content Accessibility Guidelines (WCAG). These guidelines recommend at least 4.5:1 contrast ratio for normal text (WCAG AA level) or at least 7:1 for large text (WCAG AAA level). The Colour Contrast Analyser makes it easy to test combinations of colours to ensure contrast ratios meet those official recommended levels.

In addition to contrast ratio reporting, the tool also suggests alternative colours with higher contrast if the tested combination fails to meet AA or AAA requirements. Designers and developers can quickly experiment with colour alternatives until finding a colour scheme that ensures maximum readability and accessibility for all users. Overall, the Paciello Group's free Colour Contrast Analyser takes the guesswork out of colour decisions and helps websites comply with important contrast standards.
