To paint an area with a solid color, you can use a predefined system brush, such as Red or Blue, or you can create a new SolidColorBrush and describe its Color using alpha, red, green, and blue values. In XAML, you may also paint an area with a solid color by using hexidecimal notation.

The following examples uses each of these techniques to paint a Rectangle blue.

Using a Predefined Brush:

XAML CODE:

 <Rectangle Width="50" Height="50" Fill="Blue" />

C# CODE:

// Create a rectangle and paint it with // a predefined brush.
Rectangle myPredefinedBrushRectangle = new Rectangle();
myPredefinedBrushRectangle.Width = 50;
myPredefinedBrushRectangle.Height = 50;
myPredefinedBrushRectangle.Fill = Brushes.Blue;

Using Hexadecimal Notation:

Note that the first two characters "FF" of the 8-digit
value is the alpha which controls the transparency of
the color. Therefore, to make a completely transparent
color (invisible), use "00" for those digits (e.g. #000000FF).

 <Rectangle Width="50" Height="50" Fill="#FF0000FF" />

Using ARGB Values:

The next example creates a SolidColorBrush and describes its Color using the ARGB values for the color blue.

XAML CODE:

     <Rectangle Width="50" Height="50">
       <Rectangle.Fill>
       <SolidColorBrush>
       <SolidColorBrush.Color>

    <!-- Describes the brush's color using
         RGB values. Each value has a range of 0-255.  
         R is for red, G is for green, and B is for blue.
         A is for alpha which controls transparency of the
         color. Therefore, to make a completely transparent
         color (invisible), use a value of 0 for Alpha. -->
   <Color A="255" R="0" G="0" B="255" />
  </SolidColorBrush.Color>
  </SolidColorBrush>
  </Rectangle.Fill>
  </Rectangle>
