      Effect:Color Multiply
      Category:Math and Logic
      Speed:Fast

      Description: The Color Multiply Effect produces a traditional photographic Multiply effect.

      Photographic Multiply multiplies Color 1 with Color 2, resulting is a darker picture.

      Multiply is symmetric: exchanging Color 1 with Color 2 does not change the result. If Color 1 and Color 2 contain the same values, Multiply is equivalent to a gamma correction with gamma=2.

       
      Options: The Multiply Effect has the following Options Pane:

      Multiply Red:If set to a Red X, the Red Channel is not Multiplied. If set to a Green Check Mark the Red Channel of Color 2 is Multiplied to the Red Channel of Color 1.
      Multiply Green:If set to a Red X, the Green Channel is not Multiplied. If set to a Green Check Mark the Green Channel of Color 2 is Multiplied to the Green Channel of Color 1.
      Multiply Blue:If set to a Red X, the Blue Channel is not Multiplied. If set to a Green Check Mark the Blue Channel of Color 2 is Multiplied to the Blue Channel of Color 1.
      Multiply Alpha:If set to a Red X, the Alpha Channel is not Multiplied. If set to a Green Check Mark the Alpha Channel of Color 2 is Multiplied to the Alpha Channel of Color 1.
      Output Color 1:By default this is set to REPLACE which means that the set color will be output to Color 1. You can change this as explained in Options Pane Color Mixers.
      Output Color 2:By default this is set to IGNORE which means that the Color 2 will be ignored (the original Color 2 will be kept). You can change this as explained in Options Pane Color Mixers.

      Example: The following example shows the Color Multiply Effect.

      In this example we combine three Effects. In Slot 1 we have a Texture Effect with our Arches National Park photo loaded. In Slot 2 we have a 2-Color Gradient with default values but Output Color 1 set to Ignore and Output Color 2 set to Replace:

      In Slot 3 we place our Color Multiply with default values. This is the result:
