Accessibility tests for UI contrast #8
Description
Is your feature request related to a problem? Please describe.
Color schemes have been chosen for high contrast, since this application is specifically designed for disabled users. But we have no definitive proof the color scheme is good, or protection against regressions in the future.
Describe the solution you'd like
Add an automated test that can check the contrast ratios in the UI to determine whether they meet the standards for low-vision users.
Describe alternatives you've considered
This could be periodically tested manually, but automation would be faster (and more likely to happen).
Additional context
Ideally this automation would run on PR builds, which means it will have to work without access to a real video device.
