#region

Hello,

I can in VS change color of preprocessor command, for example, to
green, but name still default (black).

My bet is that R# is not coloring these. Must be Visual Studio's own feature.
So it's up to its settings.

And second question: how I can quick create region with some name? I
select some code and want to put this code to new region.

ReSharper | Tools | Templates Explorer | Surround Templates tab — might enregion
selection with that

If this should be done for methods on a regular basis, try ReSharper | Options
| Code Editing | C# | File Layout, with its options for generating regions
upon reformatting.
