All of the colors produced by Plasma are completely saturated. Sometimes the strong colors may be distracting, and a more interesting surface will appear when you desaturate the image using Colors → Desaturate.

  | 注意
  These options are described in 第 2 节 “Common Features”.

Turbulence

  This parameter controls the complexity of the plasma. High values give a hard feeling to the cloud (like an abstract oil painting or mineral grains), low values produce a softer cloud (like steam, mist or smoke). The range is 0.0 to 7.0.

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.
