Tap your profile picture, and then select Settings > General > Theme.

2

Turn on the High Contrast Colors toggle.


 

Your iPhone and iPad also include a contrast setting built into iOS, which applies increased contrast to all supported apps, including Webex. (Settings > General > Accessibility > Increase Contrast > Darken Colors). So, if you've already applied the setting on your device, you won't be able to apply it in Webex.

Tap your profile picture, select Settings > General > Theme, and then select High Contrast.

Click your profile picture, select Settings > Advanced > Vision Accessibility, and then select High Contrast.

Then, quit your browser and sign into Webex again to see the differences.
