How to get complete list of theme colors

Hi @BitSmithy ,

Welcome to Microsoft Q&A!

You can find all system theme resources with its settings in generic.xaml which is available in the (Program Files)\Windows Kits\10\DesignTime\CommonConfiguration\Neutral\UAP\10.0.xxxxx.0\Generic.

For example: SystemControlBackgroundAltHighBrush and its color

 <ResourceDictionary x:Key="Light">
...
...
<SolidColorBrush x:Key="SystemControlBackgroundAltHighBrush" Color="{StaticResource SystemAltHighColor}" />

<Color x:Key="SystemAltHighColor">#FFFFFFFF</Color>

Thank you.
