Change Color (Background and Font) in mobile nav

Hello,
how can i change the color in the menu of tiny nav (mobile navigation)?
I did not find the right line in css.
Thankx for helping.

Tiny nav turns into select element. On some phones select does not accept styles because it is core HTML element.

You can try utting this css at end of template_css.css:

SELECT.tinynav option{
color:...
}
