Applet Customization in Cinnamon.css

[gabrieldamon42]

I have just begun customizing themes in Cinnamon. I have been able to figure most parts out but I am not sure how to customize the hover on items of drop-down menus in applets or the drop-down menus inside drop-down menus. I want to change the color of the grey menu options in this screen shot:

where is this option in the cinnamon.css file?
Thanks for any help,
Gabriel

For the drop down menus you use:

.popup-menu-item:active {
}

For the drop down menu's sub menu you use;

.popup-sub-menu .popup-menu-item:active {
}
