Wexley: Mobile Navigation Font Color

Just looking to change the font color for mobile devices only when using the Wexley template.

Here's what I used that works for tablet and mobile:

@media only screen and (max-width: 1000px){
 .folder-toggle-label, .subnav a, .page-collection a {color:white !important;}
}

Pasted that into the CSS Editor. You can reduce the "max-width: 1000px" to "640px" instead if you want it to affect mobile but not tablet.
