Smudge Brush Question(s) for artists

Some digital art programs have a “dirty brush” option or “auto clean” option for oil brush presets. The auto-clean option means the brush retains its original color with every stroke. The dirty brush feature makes the brush pick up color from the end of the last stroke and use it in the next. I have seen this feature in Artrage, Corel Painter, Paintstorm Studio, and Rebelle 3.

To get the stroke darker/lighter automatically I changed the Value option in the presets to fade (so it starts a bit darker and gets lighter), also I activated Hue to get some variation on every stroke (fuzzy stroke). Changing the Color rate was my first idea to get the “autopick” like behavior, but this basically disables every setting under the Color section.…

Not sure if something like this is actually planed to be implemented in the near future. It’s a feature I’d like to.
