The term "Brown noise" does not come from the color , but after Robert Brown , who documented the erratic motion for multiple types of inanimate particles in water.
Noise that has a frequency spectrum of predominantly zero power level over all frequencies except for a few narrow bands or spikes.

Thus, in the time domain, a few ...
