Simone-Lander Child theme change sidebar link color

I love the Simone theme (thanks Morten!) and I have made the Lander child theme (from Lynda.com). I have tried so many different ways to change the sidebar link color!
I want to change the color of the links under “recent posts” and “categories” (and the other sidebar links when I use more widgets). Right now they show up white on hover, which is a problem because the page is white. My site is: https://www.teckgoldenretrievers.com Any help would be appreciated!
