(Semi-)automatic brush/method to overpaint photographs or renderings?

[tiar]

@marcuschristopher

Actually, I’m not even looking for a fully automated mechanism like that. I would simply like to automatically pick up the color of the underlying layers while manually painting with a brush… a bit like tracing over a reference image, but without having to constantly switch layers and manually pick up colors again and again.

Damn, I haven’t implemented Sample Color Labeled Layers for color picker yet, have I
That’s something implemented for various selection tools and I want it to be in the color picker too. Then you could add a color label to the reference layer and with specific options, you would be able to use your color picker and it instead of picking from the current layer, it would pick from the that labeled layer (reference layer).

For finishing off Kuwahara effect, you can use the RGBA brushes, either those by @wojtryb or @RamonM - Version 6.0 of wojtryb's "Wont teach you to draw" brushpack relased (I’m now sure where Ramon’s brushes are, I think some are already in Krita, and some here: KDE - Experience Freedom!)
