# Default theme viewer

This tree view allows you to explore how the theme object looks like with the default values.

If you want to learn more about how the theme is assembled, take a look at [`material-ui/style/createTheme.ts`](https://github.com/mui/material-ui/blob/-/packages/mui-material/src/styles/createTheme.ts), and the related imports which `createTheme()` uses. You can play with the documentation theme object in your browser console, as the `theme` variable is exposed on all the documentation pages. :::warning Please note that **the documentation site is using a custom theme** (the MUI's organization branding). :::
