added 60 blur setting which has helped the border (see below) but the colour is still off. these were done with rct on during convert. also tried no colour transfer and lct but both were worse than these
That looks pretty good.
Try some face styling. It usually helps match colors.
Some erode would also help hide the edge color mismatch, however it will of course erode all around, including the eyebrows.
I do wish it was possible to erode differently for the top of the face (eyebrows) vs the rest of the face. I find an erode setting I need for the sides / chin ends up giving me either double eyebrows, or keeping the original dst eyebrows.
