Links are not visible unless you hover over them

Hello! I am new to wordpress and need some assistance. Anything that is hyperlinked is white text, therefore it is not visible unless you hover over it. This is happening on the main page, you can’t see the “Home” menu option (and then when you get into all other pages, you can’t see the menu option for whatever page you’re on). The bigger issue though, is anything that you can click on – blog headings, posting a comment, hyperlinked text or web sites, are not visible. I have seen a few posts about similar issues , but nothing suggested has worked and most of those posts have been just about page menus and hover text. This isn’t just an issue with my page menu, but all text you can click on. Can anyone assist, and help out a newbie? I am using the Hueman theme. Thank you!
