Change pixels to the fill color

  1. Select the Paint Bucket tool .

  2. Select a color in the Fill Color box.

  3. Set the tolerance value in the Property inspector.

    Note: Tolerance determines how similar in color pixels must be to be filled. A low tolerance value fills pixels that have color values similar to the pixel you click. A high tolerance fills pixels that have a broader range of color values.

  4. Click the image.

    All pixels within the tolerance range change to the fill color.
