How to change dropdown option background color

Hello,

I have one dropdown menu and when I run the form, that menu drops down but the background is a dark color and the letters are a dark color.

I've been trying to change the background color to a light color or even white, but it won't change.

Would you please me with this?

Thank you

You may add this custom CSS in your form to change the background of your options.

 option {

   background: rgba(150, 255, 115, 0.83);

}
