Link Color and Photo Formatting

I’m using the HighEnd Theme, with the Minimal Demo. On my pages, on the side bar, all my links are black. I can’t seem to change the color of any of these links. My site is background color is black so the links don’t show. How do I fix this?

Also, on all my pages, in my site title is custom and inside the image. On every page, there is a thick white border along the top. Is there any way I can remove this? coffeeweedsrap.com
