XAML Values

predefinedColor

One of the colors predefined by the Colors class (static properties), or one of the other named colors.

rgb

A three-character hexadecimal value. The first character specifies the color's R value, the second character specifies the G value, and the third character specifies the B value. For example, 00F.

argb

A four-character hexadecimal value. The first character specifies the color's A value, the second character specifies its R value, the third character specifies the G value, and the fourth character specifies its B value. For example, F00F.

rrggbb

A six-character hexadecimal value. The first two characters specify the color's R value, the next two specify its G value, and the final two specify its B value. For example, 0000FF.

aarrggbb

An eight-character hexadecimal value. The first two characters specify the color's A value, the next two specify its R value, the next two specify its G value, and the final two specify its B value. For example, FF0000FF.

scA

The color's ScA value as a value between 0 and 1. ScA is not exposed as a Color property directly.

scR

The color's ScR value as a value between 0 and 1. ScR is not exposed as a Color property directly.

scG

The color's ScG value as a value between 0 and 1. ScG is not exposed as a Color property directly.

scB

The color's ScB value as a value between 0 and 1. ScB is not exposed as a Color property directly.

Examples

One of the most common operations in any presentation technology is to paint an area with a solid color. To accomplish this task, use the SolidColorBrush class. There are several different ways to paint with a SolidColorBrush:

• Select a predefined SolidColorBrush by name.

  For example, you can set the Fill of a Rectangle to "Red" or "MediumBlue". The example uses the name of a predefined SolidColorBrush to set the Fill of a Rectangle.

<Canvas
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

  <!-- This rectangle's fill is painted with a red SolidColorBrush,
       described using a named color. -->
  <Rectangle Width="100" Height="100" Fill="Red" />
</Canvas>

• Choose a color from the 32-bit color palette by specifying the amounts of red, green, and blue to combine into a single solid color.

  The format for specifying a color from the 32-bit palette is #rrggbb, where rr is a two character hexadecimal number specifying the relative amount of red, gg specifies the amount of green, and bb specifies the amount of blue. Additionally, the color can be specified as #aarrggbb, where aa specifies the alpha value, or transparency, of the color. This approach enables you to create colors that are partially transparent. In this next example, the Fill of a Rectangle is set to fully opaque red using hexadecimal notation.

<Canvas 
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

  <!-- This rectangle's background is painted with a red SolidColorBrush,
       described using hexadecimal notation. -->
  <Rectangle Width="100" Height="100" Fill="#FFFF0000" />
</Canvas>

• Use property element syntax to describe a SolidColorBrush.

  This syntax is more verbose but enables you to specify additional settings, such as the brush's opacity. In the following example, the Fill properties of two Rectangle elements are set to fully opaque red. The first brush's color is described using a predefined color name. The second brush's color is described using hexadecimal notation.

<Canvas 
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
 
  <!-- Both of these rectangles' fills are painted with red
       SolidColorBrush objects, described using object element
       syntax. -->
  <Rectangle Width="100" Height="100">
    <Rectangle.Fill>
      <SolidColorBrush Color="Red" />
    </Rectangle.Fill>
  </Rectangle>

  <Rectangle Width="100" Height="100" Canvas.Top="110">
    <Rectangle.Fill>
      <SolidColorBrush Color="#FFFF0000" />
    </Rectangle.Fill>
  </Rectangle> 
</Canvas>
