How do I change the font color of my mobile search field? The site text color is white because I have a dark background, with the mobile search field font color also copying the main text color, I'm unable to see what I type in the search field when I'm in mobile view because it's a white field box.

Is there specific code for the mobile view search field that I need to reference?
