Changing Mobile Button (Hamburg) Color

Good morning. I have changed the Main Menu color to white without issue, but I can’t seem to change the color of the Mobile Button (Hamburg). It is a grey by default and I need it to be white. I have tried various classes,but nothing seems to change it. Can you provide CSS so I can make the change?



Here is to change the button menu for the mobile screen.

.slicknav_menu .slicknav_menutxt {
    color: white;

Put the code into Customize > additional CSS

Thanks Awan, did the trick!
