If it's blue, N5 over V4 any day. V4 doesn't look good with classic colors. It's a nice blue, but not great with anything but classic Cream.
As promised some ideas. I scanned some caps and took rough color values from points to try and get the closest to what it looks like. Sine there are so many rough mock ups, I'm making the one I think looks the best first, then letting you expand the others. Each set is paired with classic Cream, classic Dolch, and classic WoB.
First, since someone mentioned magenta, I did some quick mock ups of Magenta (UN33656) with Black (CR) legends:

The one I still love, but won't get made, 3B with CR legends:

Since a lot of people wanted it (but I think it looks like an obnoxious over the top CCnG), AE with CR legends (the green seems a little more dull in the mockups than when I'm looking at it in person):

Black (CR) with AE (Green), UN33656 (Magenta), UN6037 (Cyan), CV (Yellow), and 2M (Light Grey) legends:

Dolch Grey (N9) with AE (Green), UN33656 (Magenta), UN6037 (Cyan), CV (Yellow), and 2M (Light Grey) legends:

Might as well round out the bright colors with AE (Yellow) with CR (Black) legends, even if I don't care for it:

And, lastly, the often asked for Yolch with AE legends:
