Bridging the Gap Between Compliance and Design Quality
This video is featured in the UX Watch Party playlist.
Summary
After more than 20 years working in accessibility—including early accessibility projects, advocacy, education, and legislation efforts in Argentina—Santiago Bustelo believes that the missing piece is a better bridge between compliance and design practice.
In this session, he shares insights, experiments, and lessons from IPAX, an ongoing research initiative exploring the gap between accessibility compliance and accessibility adoption. The session examines why accessibility is often perceived as bureaucratic by design teams, why pair-based validation does not scale well to modern Design Systems, and whether accessibility could become easier to adopt if it also helps designers produce better design outcomes.
Key Insights
-
•
WCAG color contrast guidelines are outdated and sometimes promote poor design choices, like white on black causing visual strain for people with astigmatism.
-
•
Traditional color theory, based on a 200-year-old color wheel, is often at odds with modern accessibility needs and design quality.
-
•
Modern color models like Oklch and contrast scoring from APCA provide more precise assessments of accessible and ergonomic color combinations.
-
•
Santiago’s tool assigns scores from 1 to 5 to color combinations, balancing legal compliance with design quality to guide better choices.
-
•
Only a very limited set of colors work well against both black and white backgrounds, necessitating split color systems for accessibility.
-
•
Client resistance to changing brand color palettes for accessibility often stems from political and cultural attachment rather than technical limitations.
-
•
Presenting accessibility as enhancing brand usability for people over 40 or with common vision conditions can ease client pushback.
-
•
Responsive color systems that adapt colors across light, dark, and high-contrast modes can better serve diverse user needs.
-
•
Building accessible color systems is challenging but feasible if tools reduce the complexity and perceived risk of color adjustments.
-
•
Sustainable development of accessibility tools may require nonprofit structures and open-source licenses to attract funding and wider adoption.
