Property Value
Type: System.Byte
The sRGB alpha channel value of the color, as a value between 0 and 255.
Remarks
The alpha channel of a Color structure determines the amount of transparency the Color has. An alpha value of 255 indicates the Color is completely opaque and a value of 0 indicates the color is completely transparent.
You can set this value in XAML, but only as part of the attribute syntax for properties that take a Color, or as initialization text of a Color object element. See XAML sections and Remarks sections of Color.
