| Steps           | Number of iterations the effect takes. Lower iterations is more efficient but catches less edges to colorize. |

| Multiplier      | Amount of waves present in the colorization process. Increase to include more rainbow waves.                  |
| Black and White | If true, applies a grayscale filter to the rainbow colors.                                                    |
