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

      Description: The Color Add 1+2 Effect lets you add Color 1 with Color 2 to produce a new color. You have the ability to control which Color Channels are added, and also whether or not the Colors clip, or wrap around.

       
      Options: Color Add 1+2 Effect has the following Options Pane:

      Red 1 + 2:If set to a Red X, the Red Channel of Color 1 and Color 2 are not Added. If set to a Green Check Mark the Red Channel of Color 1 is Added to the Red Channel of Color 2.
      Green 1 + 2:If set to a Red X, the Green Channel of Color 1 and Color 2 are not Added. If set to a Green Check Mark the Green Channel of Color 1 is Added to the Green Channel of Color 2.
      Blue 1 + 2:If set to a Red X, the Blue Channel of Color 1 and Color 2 are not Added. If set to a Green Check Mark the Blue Channel of Color 1 is Added to the Blue Channel of Color 2.
      Alpha 1 + 2:If set to a Red X, the Alpha Channel of Color 1 and Color 2 are not Added. If set to a Green Check Mark the Alpha Channel of Color 1 is Added to the Alpha Channel of Color 2.
      Wrap Values:If set to a Red X, any Channel that exceeds 1.0 after the Add will be clipped at 1.0. If set to a Green Check Mark any Channel that exceeds 1.0 will wrap around. For example, 1.5 will become .5.
      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 images show the Color Add 1+2 Effect.

      We start with something simple. In Color 1 we load a pure green color. In Color 2 we load a pure red color. In Slot 1 we put our Color Add 1+2 with default values. The result is, as you would expect, yellow (remember we are in RGB space):

      The next image combines 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 the top color set to Green and the bottom to Black and Output Color 1 set to Ignore and Output Color 2 set to Replace:

      In Slot 3 we now load Color Add 1+2 and get this result:

      If we keep the same setting as the last image, but turn Wrap Values to a Green Check Mark, the same operation produces this result:

      If you compare the previous two images, the first one clipped all colors at white. The second image allowed colors to wrap around.

      The next image again combines three Effects. In Slot 1 we have a Clouds, Marble, Granite Effect. In Slot 2 we have a 4-Color Gradient with Output Color 1 set to Ignore and Output Color 2 set to Replace:

      In Slot 3 we now load Color Add 1+2 with default values and get this result:
