Menu Color

[lkjonessoc]

Where are colors defined for the underline action on the navigation? My website is www.lesliekayjones.com. Everything that is still defaulting to Blue, I would like to be able to change to a color that matches the rest of my theme. I've found ways to override all of the formatting settings except the navigation menu and font awesome feature icons, which I understand to inherit the color from elsewhere in the style sheet.
