The Windows Presentation Foundation (WPF) color names match the Microsoft .NET Framework version 1.0, Windows Forms, and Microsoft Internet Explorer color names. This representation is based on UNIX X11 named color values.
The following image shows each predefined color, its name, and its hexadecimal value.
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
In the following example uses the predefined brush Blue to paint a rectangle blue.
For a list of predefined brushes, see the Brushes class.xaml
Using Hexadecimal Notation
The next example uses 8-digit hexadecimal notation to paint a rectangle blue.
Using ARGB Values
<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>
Rectangle myRgbRectangle = new Rectangle(); myRgbRectangle.Width = 50; myRgbRectangle.Height = 50; SolidColorBrush mySolidColorBrush = new SolidColorBrush(); // Describes the brush's color using RGB values. // Each value has a range of 0-255. mySolidColorBrush.Color = Color.FromArgb(255, 0, 0, 255); myRgbRectangle.Fill = mySolidColorBrush;
