Espi finally explained to me how to configure Photoshop to color in line-drawings without either coloring over the lines or having the edges remain uncolored along the transitions from black to white, so as a test, I colored one of his old drawings, Mae:
It didn't turn out too bad, considering I really had no idea what I was doing and just wanted to see how different colors turned out with the multiply settings. It took a little over an hour. I kinda got carried away trying to do the wing's color transition. I was hoping to fade them from blue to silver, but I couldn't find a way to create silver nor transition it, so it only ended up going from dark to light blue.
