Issue with menu link color for Turbo-Portland theme

[JPrez]

Hello,

I'm using the Turbo-Portland theme and having some trouble with menu navigation link color. In the theme editor, I don't see an option to change only the menu link color. It seems the color is determined by Links under General section (see image below). 

I'd like the menu text to be white, but when I update Links under General, ALL links turn white and thus invisible in the body of pages. Changing options in the Header section doesn't change menu link color.

So, my question is how to change ONLY the menu link color?

Thanks!

Tried this, but didn't have an effect. I pasted this exactly at the bottom of styles.css.liquid:

.site-nav  a {

   color: #ffffff;

}

Hi @JPrez,

Please change code:

.nav-desktop a, 
.nav-desktop summary {
    color: #fff !important;
}
