I agree that you need black at the ends and sides of the strips before you use anything else. After that, I would put strips of green, blue, pink and gold because they seem to be the most noticeable colours ( depending on what my screen is showing me) around the black to see which one makes everything pop. But that's just me. I'm sure others would approach it differently.
