Thread:Project:Support desk/Customizing the skins top bar colour

Hi can I have some help with a skin I updated from someone else. I would like some help with customizing the top bar colour. I would like to do the colour through mediawiki:common.css please and also customizing the colour of the button and when clicked since if changing the top bar colour it would looked weird having the brown on the button whill the colour of top bar would be different. and the skin is at https://github.com/paladox2015/Metrolook/blob/master/components/tabs.less it is in the tabs.less file I am not sure though.
