Tried this with 0.9.1 and failed with an error E8001: None of the global resources with alias ‘#3E3E3E’ can be used here.

```auto
<Panel ux:Name="testing_panel" Background="#222222">
    <WhilePressed>
        <Change testing_panel.Background="#3E3E3E" />
    </WhilePressed>

    ...

</Panel>

```

`Background` is a kind of “shortcut” property that doesn’t support animation this way (we have an issue to look into doing this). You need to use the non-shortcut approach:

```auto
<Panel>
  <SolidColor ux:Name="back_color" Background="#222222">
  <WhilePressed>
    <Change back_color.Background="#3E3E3E" />
  </WhilePressed>

```

Thanks. Good to know. It’s better than adding a `Rectangle` inside the Panel and trying to change the Rectangle fill 🙂

Umm… no luck.

E8001: back\_color.Background is not a valid property path

Oops, sorry, I messed up the example, it should refer to `Color` not background:

```auto
<Panel>
  <SolidColor ux:Name="back_color" Color="#222222"/>
  <WhilePressed>
     <Change back_color.Color="#3E3E3E" />
  </WhilePressed>

```

Cool. All good.
