Unfinished painting

I wanted to achieve the effect of an unfinished painting (before "rounding off" and mixing colors), and it turned out the way I wanted, so I'm satisfied.

I'm not very good at naming things, so if anyone has a suggestion for a concise name that captures the essence, I'm all ears.

For the generation examples, I used a weight greater than one, and I've observed that the best results are achieved in the range of 1 to 1.5.
