You can customize the colours used by MC - have a look in ~/.mc/ini for a section labeled [colors] (if I remember correctly. There should be two sections to customize - one for the file manager, one for the editor.
You didn't say what colours you are currently getting. The default MC colours are a blue background with bright white for directory entries, grey for normal files, plus some other colours for specific file types (bright green for executable files, for instance). If you are not getting those colours, try finding the keyword in ~/.mc/ini and comment it out. Then restart MC and see what you get.
There should be a few sample colour schemes around - try a Google search. If you can't find anything, let me know, I can probably dig up a URL for you.
