  1. Do one of the following:

    • Alt-click (Windows) or Option-click (Mac OS) the layer mask thumbnail to select the layer mask channel; then double-click the layer mask thumbnail.

    • Double-click the layer mask channel in the Channels panel.

  2. To choose a new mask color, in the Layer Mask Display Options dialog box, click the color swatch and choose a new color.
  3. To change the opacity, enter a value between 0% and 100%.

    Both the color and opacity settings affect only the appearance of the mask and have no effect on how underlying areas are protected. For example, you may want to change these settings to make the mask more easily visible against the colors in the image.
