Dulling

This slider (1 -8) controls the randomness of the noise: a high value lowers the randomness.

Lightness

This slider changes the lightness of the noise.

Chroma

This slider changes the chroma of the pixels in a random pattern (percentage of a white of the same lightness).

Hue

This slider changes hue of the pixels in a random pattern. It selects an increasing available color range in the HSV color wheel starting from the original pixel color.

Random seed, New Seed

This option controls the randomness of the filter. The Random seed box lets you manually enter a seed for the randomization algorithm used. You can also generate a random seed by pressing the New Seed button. If the same random seed is used in the same situation, the filter produces exactly the same results. A different random seed produces different results.
