The pattern looks like an enlarged patch of fog or cloud: its soft regions flow into one another without hard edges. It works well when a screen needs natural color variation instead of a flat fill.
`scale` defaults to 2 and ranges from -2 to 5; increasing it makes the pattern finer. `contrast` defaults to 0 and ranges from -1 to 5; higher values sharpen color transitions. `speed` defaults to 1 and ranges from 0 to 5; higher values make the pattern change faster. `balance` defaults to 0 and ranges from -1 to 1, shifting the mix toward the second color below zero and the first above zero.
This is a generator that fills the canvas, not a filter that transforms input. Use it as a background on its own or layer it with `FractalNoise` for variation at more than one scale. If text sits over it, keep `contrast` low enough for the text to remain readable.
When to use
Use it for foglike backgrounds, organic color patches, and slowly moving abstract scenes. Avoid it when you need a repeating grid or crisp pixel edges.
