In Corel Painter, there is a feature to use clone source as the source for colors. In this feature, it automatically picks up the color of the clone source or underlying layer if it is designated as the clone source. This is much easier than selected each color with the picker each time. Is there a compatible way to do this in Krita?
No, there isn’t. However considering the work I’ve done in Contiguous Selection Tool and Fill Tool with color labeled layers, I believe it would be possible to add this to the color picker as well. It’s not implemented yet right now though.
