Winui3 Button color?

Question

Hi

Hi got a question on button color - now this is coming from a WPF point of view.

It looks like the default buttons are not grey like the are in WPF.

First question is I am assuming it is some guideline that I am not understanding.

Plus is there some documentation to point me to as to be honest it does not contrast as well to WPF defaults. In respect to the button background and the surface (Window) it might appear on.

Thanks

Answer 1

All colors are defined in generic.xaml

For button, you can see

 <StaticResource x:Key="ButtonBackground" ResourceKey="ControlFillColorDefaultBrush" />  
 <StaticResource x:Key="ButtonBackgroundPointerOver" ResourceKey="SystemColorHighlightTextColorBrush" />  
 // etc...  

then

 <SolidColorBrush x:Key="ControlFillColorDefaultBrush" Color="{StaticResource ControlFillColorDefault}" />  

then

 <Color x:Key="ControlFillColorDefault">#0FFFFFFF</Color>  

So they are partially transparent, depending on the parent background color
an can be changed in XAML in ResourceDictionary.ThemeDictionaries for example

The design guidelines that WinUI3 follows is documented here. As always, if you don't like the defaults then you can customize to use your own theme. The defaults are discussed here.
