Modify controls for the Colorama effect

Modify controls specify which properties are modified by the Colorama effect. Once the Input Phase pixels are mapped to a color on the Output Cycle, the results are applied to the property selected here. You can get a great deal of selective control by choosing the same property for the Input Phase and the Modify property, along with an appropriate Output Cycle.

Note: Because the input layer is represented as a grayscale file, the Ramp Grey preset palette works well and is most predictable with any Modify setting other than All.

Modify

Specifies the specific property to be modified.

Modify Alpha

Specifies whether the opacity information in your Output Cycle is applied to the output. Selecting Modify Alpha changes the alpha information along with the other channels selected from the Modify menu. Modify Alpha works in conjunction with the Change Empty Pixels option in determining the final change in opacity.

Note: If you apply Colorama to a layer with an alpha channel, and the Output Cycle does not contain alpha information, the anti-aliased edges of the layer may appear pixelated. To smooth the edges, deselect Modify Alpha. If Modify Alpha is selected and the Output Cycle contains alpha information, the output is affected even if you've selected None from the Modify menu. This is how you can adjust the levels of just the alpha channel without also changing the RGB information.

Change Empty Pixel

Specifies whether you want Colorama's effects to extend into the transparent areas of your layer as well. (This works only when Modify Alpha is selected.)
