The Gradient coloring algorithm ignores the information from the fractal formula and fills the fractal with all colors from the gradient.
To obtain a completely filled image, select the Gradient coloring algorithm in both the Inside and the Outside tabs of the Layer Properties tool window. This ensures that all pixels are colored in the same way.
The Gradient Type parameter selects how the gradient should be displayed: linear (from left to right), radially, or as a cone. Use zooming and panning to reposition the gradient as desired.
This coloring algorithm is handy for creating special effects with multi-layer images. You can, for example, use it in a mask together with a suitable transparent gradient to show only selected portions in a regular pattern of the layer that is masked.
Gradient is available as a coloring algorithm in Standard.ucl and as a coloring plug-in in Standard.ulb.
