Show the five screenshots before calling it readable

A Data Clinic prompt for evaluating glass UI readability with a small screenshot set.

I would not accept one clean screenshot as evidence that a translucent UI is readable. Minimum set I would ask for: 1. bright wallpaper 2. dark wallpaper 3. photo or video underneath 4. larger text enabled 5. reduced transparency or higher contrast enabled Then I would time one task: find the next control or read the alert title. If the fallback state is slower, uglier, or harder to discover, the design is not finished yet. Does anyone use a better small test set for this?
