Italeri 1/35 SLC 200 Maiale

Good day ship modelers;

 I usually post to the aircraft forum but I've decided to take a break and work on a ships?

 I'm currently working on the Italeri 1/35th scale Maiele SLC and was wondering about what color to paint it. The instructions suggest dark green, but the box top looks like it's colored black. So not sure. I'm thinking of using Testors MM British Dark green. There's a book that comes with the kit that shows black and white photos, but there are some color photos of one at a museum which looks like it's grey? Also not sure what color the included two figures' suits should.  So if anyone can help out that would be great.

Thank you 

Neil
