Introduction

Colour functionality can make or break your website and digital assets. Some colour combinations are welcoming to everyone, others create barriers. Choosing the wrong colours can exclude people from engaging with your organisation, impacting your business and brand.

To ensure your web assets are visually accessible and meet Web Content Accessibility Guidelines (WCAG 2.1), we have compiled a selection of the best resources for analysing and checking colour palettes and contrast for digital design.

Digital Access also offers on-demand training in Colour Accessibility, arming design teams and professionals with essential skills in inclusive design.

Colour contrast checkers

Using a colour contrast analyser tool or plugin is a useful way to determine the legibility of text and images on a web page or document, based on WCAG 2.1 requirements.

Note: Vision Australia Colour Contrast Analyser

Please note the Vision Australia Colour Contrast Analyser has been discontinued. The software has been superseded by the TPGi Colour Contrast Analyser (CCA) listed below.

Colour blindness simulators

Installing an extension to your web browser can simulate various types of colour blindness and visual conditions.
