I know you were asking for colors, this is another way:

set statusline+=%{strpart(&ff,0,1)} " fileformat

In my statusline that is the last item and is right justified.
It displays only the first character of either unix, dos, or mac,
leaving room for other status info.

&ff is the fileformat variable
strpart returns 1 char starting with the first (0 based)
