Full disclosure? I always love the way clean lineart looks but never feel like mine is finished. This is an auto action to give lines a little extra "oomph" . Can be used on plain linework or fully colored pieces but works best when there is some detectable value change.
Try with complementary colors to your pallete
THANKS
