- Activate the Differentiate without colour option (Settings > Accessibility > Text display and size > Differentiate without colour).
- Identify on the screen words or sets of words, texts, graphic elements conveying information and time-based media whose colouring conveys information.
- Check that there is another visual way of retrieving this information: the presence of an icon or a graphic effect of shape or position, a typographic effect, etc.
- Using the screen reader, access the information provided by the colour.
- Check that equivalent information is rendered by the screen reader (for example the "selected" status of a green button).
- If this is the case, the criterion is validated.
