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 Layer/Colors/Desaturate.

	Note
	An enhanced version of the Plasma plug-in, called Plasma2, with many more options and parameters, is available from the GIMP Plugin Registry [PLUGIN-PLASMA2].

13.3.2. Activating the filter

Random Seed: Random Seed controls the randomization element. The Randomize check-button will set the seed using the hardware clock of the computer. There is no reason to use anything else unless you want to be able to repeat the exact same pattern of randomization on a later occasion.
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 0.1 to 7.0.
