Purpose
To enhance the visual accessibility of teaching materials by identifying key concepts and best practices, using freely available tools to apply these concepts to the redesign of our curricular calendar, and demonstrating the use of these tools through a case study of the redesign process.  Visual accessibility of teaching materials is an important consideration for teaching and learning in a virtual digital era.  Public universities' teaching materials must meet visual accessibility standards, per a 2024 update of Americans with Disabilities Act (ADA) regulations.  Color vision deficiency (CVD, or color blindness) affects ~8% of men and 0.5% of women, and impacts perception of a wide range of colors. Color is often used to convey information, yet selection of CVD-accessible color schemes and related best practices are sparsely represented in the medical education literature.

Methods
We identified key concepts and best practices from sources including federally mandated visual accessibility guidelines.  We used free, validated tools to check the visual accessibility of our curriculum calendar and redesign it for enhanced accessibility.  This project illustrates several key concepts.  Using it, we will demonstrate the implementation of best practices using these tools.  

Results
Key concepts we identified included the importance of contrast between font and background; selection of CVD-accessible color combinations; and dual encoding (providing more than one way to distinguish information).  We identified color combinations in our calendar’s color coding scheme that are not distinguishable for people with common forms of CVD, including pink/purple/blue/gray and peach/yellow/green.  We redesigned the calendar to increase contrast, make colors more widely accessible, and use dual encoding.  

Conclusion
Accessibility of electronic resources is a key consideration for medical educators.  This importance is underscored by recent updates to federal accessibility regulations.  The redesign of our curriculum calendar enhances accessibility for all members of our community; further work will evaluate the impact of the redesign on faculty awareness and use of tools to enhance visual accessibility.  Attendees can apply the tools and techniques described to check and enhance accessibility of their own materials with minimal time and effort.
