You can choose the color of the shadow here. Just click on the color swatch, and select a color when the color selector pops up, or use the eye-dropper to pick a color from the image.

Composition

The “Output composition” selects how the output of this filter will be determined. There are three choices:

Shadow plus image will output both the input image and the created shadow. This is the default.
Shadow only will output only the created shadow.
Shadow minus image will output the created shadow but subtracts the area hidden by the image.
