Make Your Slides Accessible: Check Your Color Contrast
To ensure your presentation is accessible to all attendees, especially those with color blindness, please follow these color contrast guidelines:

• Maintain at least 4.5:1 contrast between text and background for standard text
• Use at least 3:1 contrast for large text and graphical elements

We recommend using the free Contrast Checker tool to test your color combinations. Simply select your foreground and background colors to see if they pass, are borderline, or fail the contrast requirements.

Accessible slides make for a better experience for everyone. Thank you for taking the time to check!

In collaboration with the National Center for Women in Technology (NCWIT), the Linux Foundation has created an online course designed to teach the viewer about inclusion, diversity, and unconscious bias. We highly recommend all of our speakers watch the course to learn tips/tools to use when speaking to encourage inclusivity in presentations and messaging. 

Along with the online course, we suggest that speakers also refer to the Inclusive Language Initiative’s language recommendation list, which provides guidance on substituting hurtful and exclusive language in the field of information technology.

Ensure compliance with our Event Code of Conduct, prioritizing inclusivity and appropriate language and imagery in your presentation.
