Insufficient 3:1 contrast ratio for certain button texts in Canvas:
The 3:1 text for the published buttons (for example pages), discussion subscription buttons, and the "Course is Published" text (in course settings) are only 14px and 16px in size. So the size needs to be slightly increased in order to meet the AA requirement. Alternatively, Instructure could change the contrast slightly to ensure that these 3:1 texts meet the WCAG 1.4.3 requirement for both regular and large text sizes, without having to change the size of the texts.
Regardless of the user's ability to resize text and regardless of the High Contrast UI in Canvas, accessibility should be the goal in the Standard UI - so Instructure should make sure these texts fully meet the WCAG 1.4.3 requirement.
I have tried to explain this to Instructure in Canvas Cases a few times but they still do not understand/acknowledge that the text sizes are too small and keep saying that everything is OK if the user uses the High Contrast UI. To me, the High Contrast UI is not an excuse to circumvent accessibility requirements for the Standard UI.
I know this is a small thing to request, but the constant back and forth in Canvas Cases is increasingly frustrating. If I am mistaken, please prove me wrong 🙂
