- Choose the frames and activate the layers of the colored animation we require.
- Make a copy and paste of this data to some other empty layers.

- Select the previously copied cels.
- Select the Brightness function and set it to its maximum value.
- Approve the operation by pressing OK.
- Repeat steps 5 and 6 until the shape of the selected animation is totally white.
