agreed and aside from the lack of colour the big bug bear for me is also the little oval/square button that used to show and hide the sidebar in one operation
mount a data disk on your desktop and open it, by default (can this be changed?) you get a minimistic finder window opening with no toolbar and no sidebar - one could easily ask why?
anyway in older versions SL and earlier you pressed the little button on the right of the toolbar (where the full screen option is now) and the toolbar and sidebar would appear.
Now you have to go up to the menu, choose sidebar (which doesnt work due to a bug they havent fixed yet) then choose show toolbar then choose show sidebar one more time and finally it appears otherwise it is open a second finder windows with Cmd N which oddly opens with the sidebar open so you can copy files from one finder window to the other - I mean this is so archaic
