[OPEN] a11y Reply button in Discussion Redesign split screen view has less than 3:1 contrast


Engineers are currently investigating the issue.


When viewing discussions using Discussion Redesign in the split screen, the button to reply to a thread or indicating how many threaded replies there are has a color contrast of less than 3:1. Additionally, we are not meeting 4.5:1 contrast ratio via the High Contrast UI feature option.

Expected Behavior

The default color ratio should be 3:1 or higher, and the ratio should be at least 4.5:1 when HCUI is enabled.


No workaround exists at this time.

Steps to Reproduce

Prerequisites: Course with Discussion Redesign feature enabled

  1. Create a discussion. Make a reply, and a threaded reply.

  2. Check the option to view the split screen.

  3. Click Reply on the post, or click the 1 Reply button. In either, notice the light button in the split screen view.
