Active link on sticky menu and top bar color

Hi, guys! 2 questions:

1. How can I choose the active link color on sticky menu? Mine is the same color as the background, so I can’t see the selected page. Here:

2. about register/login/my account: I turned it on on theme options, but it’s not showing unless I turn the top bar option on… so can I change the top bar and links color? The background is currently black with white links, and I would like to have white background with main color links, so it blends with the header.

Thanks a lot!
