Header not customizable – Auction theme

Hi,

I am using the acution theme and I am trying to edit the header. There are some nice templates and I found one close to what I want. However, it seems like I can basically only edit the background color of the header, not the text color or even remove some of the menu items from the header. Is this intended or am I missing something?

In the attached file I don’t want the links on the rights for example (Home, About us, Contact). I also want to change the text color of the button to something dark but I can only seem to edit the background of it. How do I edit text colors in general in the header? Or in general add/remove items to the header such as new links?
