Do you want a deeper blue? I did not go too dark, but I can. Unfortunately, what appears as a "dark navy" blue on screen prints as a violet/purple color with both offset and digital printing. So I can adjust my art to look "dark navy" for the sake of viewing on the monitor but then adjusting the color back so that what you see on screen is what will print. I noticed that you asked for a 2 color version. Is keeping to 2 colors a preference, or an economical issue for printing? As I have to tell all my clients, because of how offset printing is done today, it is far less expensive to print full color (CMYK) then to print 2 spot colors. Most people that ask us about printing 1 or 2 color usually figure it is cheaper. I mention this because the old school of thought was that the fewer colors, the less expensive - today that is no longer true in most parts of the world.
