This variable specifies how intense the color of the squares should be. This affects the opacity of the squares. A high value will render the squares very intensely and does not allow lower squares to show through. A lower value allows the lower squares to be more visible through the higher ones and causes more blending in the colors.

This allows you to change the background color that is used by this filter. You can click the color bar to select a color, or use the color picker to pick a color from your image.

The randomness in this filter is based on a so-called seed. Different seeds will cause the output of the filter to change. You can change the seed until you find a preview that you like.
