This effect keys the layer based on a color of your choice. You can use the hue or RGB values to generate the key.
- Color: Choose a color to be removed from the layer. You can use the eyedropper to choose a color from the layer, or click the swatch to open a color picker and choose any color you prefer. You can also manually enter the color values for the red, green, and blue channels.
- Tolerance: Controls the range of hues surrounding the exact color you have chosen, which will also be removed.
- Edge Softness: Applies a blur to the matte generated by the key, to soften its edges.
- Match Colors By: Select whether colors are matched based on hue, or RGB values.
- Invert: Reverses the results of the key, so only the selected color remains, and all other colors are removed.
- View Matte: Toggling this option displays the matte on the viewer, as a grayscale image where White is completely retained, and black is completely removed. This can be useful for identifying problem areas which may need further adjustment.
