In the following, we're going to override the default light theme color of the app:
* Unpack the default XAMLs;
* Pick and deploy the default UBIKThemes.xamlx to the '''xaml''' folder inside the ''LocalState'' folder:[[Image:setup-themes-file.png|frameless|600px|border]];* Open it with the text editor of your choice and remove everything within the '''ResouceDictionary''' except the following <syntaxhighlight lang="xml"code><Color x:Key="UBIKLightThemeColor">blue</Color></syntaxhighlightcode>;
* Save the changes and reload. You should see changes successfully implemented.
