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.
