I checked the `Tab Navigator options in React Native` and unfortunately, background color is not part of them. So this option will not work.

I’m referring to this article  
[https://reactnavigation.org/docs/tab-based-navigation/](https://reactnavigation.org/docs/tab-based-navigation/)  
However, Thunkable might be using an external solution for the navigation in which case will will not know what options are available.
