       <!-- Primary brand color. -->
       <item name="colorPrimary">@color/purple_200</item>
       <item name="colorPrimaryVariant">@color/purple_700</item>

       <!-- Secondary brand color. -->
       <item name="colorSecondary">@color/teal_200</item>
       <item name="colorSecondaryVariant">@color/teal_200</item>
       <item name="colorOnSecondary">@color/black</item>
       <!-- Status bar color. -->
       <item name="android:statusBarColor">?attr/colorPrimaryVariant</item>
       <!-- Customize your theme here. -->
   </style>
</resources>
