I am trying to get back into my coloring work but it is not like riding a bike. i can't remember anything. My question is, first of all a tutorial would help but second if not... How do i separate the non photo blue from the black ink and penciled artwork? Specifically the page borders on the comic book lined paper. I would do a Google search, and i have, but I am not sure how to specifically ask the question to find the correct results.
