Select Country: Ability to change color of selected country.

I want to  know  if is some CSS code to  change the color that appears when i select a country  in widget called select country 

The number is #660099

There's not a way to change the colors used in the Select Country widget, they're set up with some code that cannot be handled through the form builder and injecting some CSS code to the form will not work. 

I will forward this thread as feature request to our second level, do note that although we cannot provide an ETA or ensure this will be implemented, we will let you know as soon as we receive any update regarding this.
