You want to put monochrome and sketch in the Negative Prompt if you want everything in color and if you want it to look like the comics, put Monochrome, sketch, lineart in Positive prompt and delete any color words in the trigger. If you want, you can put black lips and pink lips in the Negative prompt for her plump bottom lip.

I would link to the artist to support them but they recently deleted their work and quit :(
