Connections theme colour

Hey,
Looking for some help with the Connections theme which I am using currently on https://www.digitalsole.net(a wordpress hosted blog). I am working on a new site with my own installation with this theme and making a custom header for this but cant match the colour with the links menu across the top(if you take a look at https://www.digitalsole.net you’ll see the difference). I have tried every code in the stylesheet but cant match it. Anyone know how or where I can find this?
