Hi. I made a video showing 3 different techniques to change the color of part of an image (be it a photo or illustration): the color blend mode, the HSL/HSV adjustment filter using chromaticies and luma, and a combination of the filter plus color adjustment curves. The video includes workflow tips and Krita features on masking, and the advantages and drawbacks of each method.
