Hi Babita,

I hope you are well today and thank you for your questions.

How do we change scroll down menu colours?

You can change its color by adding the following CSS code in the Custom CSS option of your theme on the below path.

Admin Area -> Appearance -> Customize -> Additional CSS

.dropdown-menu> li> a{
    color: #000;
}

You can change the color value in the above code to whatever you want to use by referring the following pages.
