Guy, the bottom view and the other three, it's all the same grey. The flash seems to make it very light coloured for some reason. The black-green is actually Glossy Sea Blue (Humbrol H181). Once the decals are on I'll take some pics in natural daylight, probably on the weekend.
The paint scheme in the first 3 photo's looks like black-green on white, which would be an awesome Norwegian fjords scheme.
There's two types of fin/rudder to choose from, one is a short one with a broad chord rudder, the other is a tall one with short chord rudder. I'm using the tall one but I'm making it taller still.
