Two questions for you experts

[Hitman]

Colors in the navmap have nothing to do with sonar conditions. It's just combination of depth and slope direction (3d shading). I'm writing this for like 10th time, but it's needed it seems.

I had been told by someone else that colours had to do with sound transmission...

I remember there was a key combo to disable them :hmm:

And what about the periscopes? Anyone has a link to good information of modern US/Russian periscopes?

Thanks

I've heard that rumour also. But when you take a good look at seabed features you'll notice the darkness is allways on the same side of it (lower side iirc), no matter where on the world it's at. So it must be some kind of gradient/slope thing like Dr Sid said. As accoustics it makes no sense.

Exactly, light blue = shallow water, deep blue = deep water.
Nothing more, nothing less.
The colors don't represent sonar performance per se, but if you consider the underwater mountains and valleys then yes they give topographical information on where to hide for maximum effect and where to listen to achieve maximum performance.
