# Customize ## Theming Your App Making changes in the app that you want is much simpler. It's designed in a way to handle changes and to make the whole process easier. * The theme has separate file inclusive of colour schemes for the whole app. * The theme allows you to change name, logo and splash screen of the app * The theme has separate screens so making changes in one screen would not effect other screen ### Change App Colors To customise the colour scheme for the app you need to make changes in one file only `src/utils/colors.js` set the colours that you require in this file it should reflect throughout the app. ### Change Icon and Splash image * **Expo**\ \ With [Expo](https://expo.io) changing the app icon is much easier. You need to replace the icon inside `assets/icons.png` similarly if you want to change the splash screen you need to replace the image in `assets/splash.png` with your own image. ### Rename App * **Expo**\ Renaming app name is pretty straight forward just replace the `name` attribute inside `package.json` ### Changing the URL name for publishing with Expo * To change the App name for the Expo url, you just need to rename the `slug` attribute in `app.json` file. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
