UWP allows you to take full control of the advantages of Windows 10. Some of these advantages are graphical, as the Accent color or Dark/Light themes.

To prepare your app to be compatible with these feature, a bunch of premade colors have been implemented in UWP to change with the Accent color of the OS the program runs on, or with the theme choice of the user.

There are two "ways" of doing this :

  • Diretly in Xaml, using the Color = {ThemeResource x} Attribute (or whatever attribute that takes a Brushas value, like BorderBrush, Background, etc.)

  • In C# Code Behind, by Searching for the color in the Resource directory of the current app. This gives a Color object, so if you want to put it in the Color property of an object you referenced from your Xaml, you'll need to make a new brush like this :

new SolidColorBrush(Application.Current.Resources["yourColorKey"])
