Color change during hover

When I move my mouse over pages on my site (such as the home page of http://www.lionreach.com/), my white font becomes teal colored. It goes back and forth, actually. Please help me to locate the feature that controls that behavior–I need to either make it stop, or change the colors to match each other. Troubleshooting performed: In the styles.css, I searched for the term “hover.” Each time I saw a color associated with it, I changed the color to purple, to see whether my teal becomes purple. The testing failed, since purple never expressed itself on the page. Thank you in advance for any help.
