Change the colour of the Admin Panels from blue

Hi Guys

I'm hoping that someone can provide myself with a little information.

Once i log into my Admin Panel i was wondering if i can change the blue Panels to a different colour. I'm looking at changing it to green.

I've tried changing the stylesheet but so far nothing has worked. Has anyone done this before and know which is the correct file that i need to edit.

Thanks in advance.

admin>view>stylesheet>stylesheet.css
they are located right under /* Tiles */
change the next three

background-color: (Hex Value);

then empty your browser cache
then reload the admin panel.

Thaks for all your help
