https://litter.catbox.moe/b11ir1vhnw6dr0h8.pngWorkflow is super simple. Use the Load image node to load an image, the right-click the node, Open in Mask Editor and draw a mask for the inpaint area. Change the denoise setting depending on how much of a change you're making, color-wise.
Optionally, edit the prompt to include only what is (or will be) in and around the inpaint area, some overall context like time of day, background, etc and anything you need for style. More important the higher your denoise is.
For best results, open up an image editor and draw a rough blob in the shape and color of your intended result. This lets you keep denoise much lower and makes the inpaint far more reliable. Or you could just keep rolling seeds.
