It is often thought that accessible documents cannot be colorful, beautiful or complex. In this session you will learn how to select colors that work together to present the most inclusive and accessible material.


Get useful information about accessible color palettes, color as a differentiator and tools you can use to identify low vision color contrast and colorblind barriers. We will also be covering the following WCAG Success Criteria and how they play a part in validating your content: • 1.4.1 Use of Color • 1.4.11 Non-text Contrast • 1.4.3: Contrast (Minimum) • 1.3.3: Sensory Characteristics


  1. Accessible color palettes do not need to be simple black and white variations.
  2. Good color contrast benefits everyone - not just those with low vision or colorblind barriers.
  3. Understanding what makes a color combination accessible empowers designers with creative freedom.
