XAML Values

predefinedColor

One of the colors predefined by the Colors class.

rgb

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

argb

A four-digit hexadecimal number. The first digit specifies the color's A value, the second digit specifies its R value, the next digit specifies the G value, and the final digit specifies its B value. For example, F00F.

rrggbb

A six-digit hexadecimal number. The first two digits 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-digit hexadecimal number. The first two digits 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

System.Single

The color's ScA value.

scR

System.Single

The color's ScR value.

scG

System.Single

The color's ScG value.

scB

System.Single

The color's ScB value.

profileUri

System.Uri

The International Color Consortium (ICC) or Image Color Management (ICM) color profile.

alphaValue

System.Single

The alpha channel color value. The value range is 0.0 to 1.0.

colorValue

System.Single

A comma-delimited list of three to eight values that represent the color channels of the color profile. The value range is 0.0 to 1.0.

The Color type exposes the following members.

  NameDescription
Public propertyAGets or sets the sRGB alpha channel value of the color.
Public propertyBGets or sets the sRGB blue channel value of the color.
Public propertyColorContextGets the International Color Consortium (ICC) or Image Color Management (ICM) color profile of the color.
Public propertyGGets or sets the sRGB green channel value of the color.
Public propertyRGets or sets the sRGB red channel value of the color.
Public propertyScAGets or sets the ScRGB alpha channel value of the color.
Public propertyScBGets or sets the ScRGB blue channel value of the color.
Public propertyScGGets or sets the ScRGB green channel value of the color.
Public propertyScRGets or sets the ScRGB red channel value of the color.
