Hyperlink Color

I am using the Unconditional theme for my website. I wanted to change the colors of two things.

First, I’d like to change the main site title color (the one in the center of the homepage over the photo.

Second, when I hyperlink items in the main text of the site, they still look black and are the same font as the rest of the text. Is there a way to make the hyperlinked words appear in a different color so that they stand out?

Thank you!
