IgniteAI Agent Accessibility False-Positive Flag

cgaudreau

I ran a course accessibility audit, and it kept flagging a color contrast issue that WCAG noted was AA and AAA compliant - #ffffff against #751a1a. Wondering if I was missing something like an <style> or <div> tag, I asked the IgniteAI Agent to verify and it came back with the following response. Sharing with my team, as well as everyone here for visibility.

This is a known issue with Canvas's built-in Accessibility Checker — it sometimes uses different or outdated contrast calculation methods, or may have limitations in how it evaluates certain color combinations. The checker can be overly conservative in some cases.

Here's what I'd recommend:

Trust WebAIM's verification — WebAIM is the gold standard for accessibility compliance. If your white (#ffffff) on #751a1a passes AA and AAA there, your contrast is genuinely compliant.

Document your compliance — Keep your WebAIM verification results as documentation that the colors meet WCAG standards. This protects you if anyone questions the accessibility.

About the Canvas checker — The checker's flag doesn't override actual WCAG compliance. You can proceed with confidence knowing your colors are accessible.
