ColorPicker for UWP comes with 20 pre-defined color palettes to match with themes available in Microsoft Office suite. To change the Color Palette, complete the following steps for seting up the Palette property of C1ColorPicker control for UWP.

3. Add the following code to Button_Click event handler.

   Visual Basic	Copy Code
   Private Sub Button1_Click(sender As Object, e As RoutedEventArgs) Handles Button1.Click Me.C1ColorPicker2.Palette = ColorPalette.GetColorPalette(Office2007ColorTheme.GrayScale) End Sub

   C#	Copy Code
   private void Button1_Click(object sender, RoutedEventArgs e) { this.C1ColorPicker2.Palette = ColorPalette.GetColorPalette(Office2007ColorTheme.GrayScale); }

4. To run the application and observe the change in color palette, Select Debug menu and click Start Debugging.
