Christopher Schmitt explores color theory, color perception, color blindness, and accessible web design. Learn how WCAG addresses color, contrast, relative luminance, and contrast ratios, plus techniques and tools for evaluating color accessibility and creating more inclusive digital experiences.
color contrast
Color contrast is a fundamental part of digital accessibility, helping ensure that text, controls, icons, and other meaningful visual elements can be perceived by people with low vision, color vision deficiencies, and other visual disabilities.
This collection of 24 Accessibility articles explores color contrast from practical, technical, and strategic perspectives, covering WCAG requirements, common contrast challenges, testing approaches, design considerations, and the impact of contrast on real-world user experiences. Together, these articles provide valuable guidance for designers, developers, accessibility professionals, and organizations working to create more accessible and inclusive digital experiences.
Color Contrast, Beyond the Basics
Beth Raduenzel explores why passing WCAG color contrast requirements does not always create an accessible experience. She examines links, focus indicators, navigation, toggles, form controls, and maps, showing how designers can improve contrast and usability for people with low vision.
