The NowWebTheme interface provides properties that enable you to override the colors used within web pages hosted on your ServiceNow instance in a native web view.
The NowWebTheme interface extends the NowUITheme interface and inherits the property nowUIColoring.

`val nowUIColoring: NowUIColoring?`

This property is used to reference color variables that NowWebTheme can use. For additional information on how to theme the UI, see [Use NowUIColoring to theme NowWebTheme and NowChatTheme](https://servicenow-prod.fluidtopics.net/4JlbfpTx8wi5Ua0_FoaKdQ "The NowUIColoring interface contains all the colors used by all NowSDK modules.") in the Mobile SDK Developer Guide - Android.
