Sub-menu (drop-down menu) colors (hover and non hover)

Hi,

I am using Fluida for my wordpress site.

Can someone please tell me how to change the background color and the background hover color for the drop-down menu items?

I have managed to change the background hover color for the main menu using the following custom CSS that I found elsewhere in this forum:
body #access > div > ul > li:hover { background: #300447; }
body #access > div > ul > li:hover a { background-color: #300447; }

However, i don’t have the knowledge to do the same for the drop-down menu items.
At the moment they are showing black font color on dark purple background. I would like black font on white background, with white font on dark purple background for hover.

Thank you for your help.

Nina
