Q:

Setting background of panel with custom color code

In WPF,I can set the background of a stack panel using the below code
stackPanelFlasher.Background = Brushes.Aqua;

How  can I set the color as a hex color code for example #C7DFFC?

A:

BrushConverter bc = new BrushConverter();  
stackPanelFlasher.Background=  (Brush)bc.ConvertFrom("#C7DFFC"); 

Should do the job. If you want to make it waterproof, better would be 
BrushConverter bc = new BrushConverter();  
Brush brush=(Brush)bc.ConvertFrom("#C7DFFC"); 
brush.Freeze();
stackPanelFlasher.Background=brush;

needs fewer resources...

A:

stackPanelFlasher.Background = new SolidColorBrush(Color.FromArgb(alpha, red, green, blue));

I think this sample helps you for xaml solution;
 <Border.Background>
       <LinearGradientBrush EndPoint="1.204,0.5" StartPoint="0.056,0.5">
           <GradientStop Color="#FFFFFFFF" Offset="0" />
           <GradientStop Color="#FFD4D7DB" Offset="1" />
       </LinearGradientBrush>                     
  </Border.Background>
