Hover color of custom widget in header

Hi,
I have added a custom widget in the header. I also added a link to it using the following code:

add_action( ‘ava_after_main_menu’, ‘enfold_customization_header_widget_area’ );
function enfold_customization_header_widget_area() {
echo ““;
dynamic_sidebar( ‘Header’ );
echo ““;
}

I would like the widget hover to be the same color as the non-hover. My header is transparent and changes color when I scroll. How can I control the hover color for both unscrolled and scrolled header?

Thank you!
