Filter-effects may be applied to one of several layers in an image to achieve widely different results.

A collection of my experiments to affect a watercolor painting style using the two-dimensional, Inkscape drawing software.
Below are some other examples of filter effects applied to the same shapes, for comparison.
The background gradient is a gradient blend. The technique for achieving this effect is described elsewhere in this blog. It is not built into Inkscape like the filters used to create these examples.
More filter-effects experiments.
Two brush tools were used in this painting: wiggly and brush.
Different widths and transparencies were set also: wider and more translucent for pastels and thinner darker contrasting colors in the foreground.
I am not happy with the foregorund, so this painting still needs work.
