generative fill

I feel like you guys should work on a command that works with the color wheel or color palette of an image. For example, there's a patch of the image I like so I put it into generative fill so I can make that patch match the color I want. I was thinking the user can write something like " I want a darker shade" and it gets filled in. or they can choose the color they want if the command doesn't fix what they want.
