Change themes colors

Yes it is, go into Appearance > Theme Options and change some items there.
Items not listed in there will need to changed through the custom csss section.

Yes, background… but i need to change menu colors, and colors in posts, date and borders (or it looks like borders anyway) for exempel.
I understand it have to be in css section:) but how? what selector it is?

If you can provide a link we can look through the code to determine that.
As far as the menu you can change in the Theme Options section (background, menu buttons color, text and text on hover colors).

At the moment theme don’t have general color scheme configuration. We will think about implementation this feature in next theme version.

You can choose colors for menu, via theme option. Other styling possible only via custom css.

Links color

.content a {color:#000}
