Color.Addition Operator (Color, Color)
Adds two Color structures.
Assembly: PresentationCore (in PresentationCore.dll)
Color structures are added together by adding the alpha, red, green, and blue channels of the first color to the alpha, red, green, and blue channels of the second color. For example, the alpha channel of color1 and the alpha channel of color2 are added together to produce the alpha channel of the resulting color. The same is done with the red, green, and blue channels to produce the red, green, and blue channels of the new color.
